Crash NTDLL.dll

[AHunt]

I have Lightroom Classic 14.1 installed. Here is the system information:

I installed Lightroom Classic 14 as soon as it was available and then installed 14.1 when it was available. Everything has worked fine until yesterday. LrC started "going away" after two or three minutes of use.  At first it sometimes would display the crash report dialog, but now it does not do that. Whenever given the chance I report the crash. I have tried the following:

• Rebooted my computer
• Tried with GPU both off and on in preferences.
• Reinstalled my graphics driver.
• Reinstalled LrC 13.5.1. It works fine with no issues.
• Reinstalled Lightroom Classic 14.1 and the crashes reoccur
• Deleted Lightroom Classic preferences and restarted Lightroom Classic, it still crashes

Every time this happens, the Windows Event viewer shows an "Application Error" with Task Category of "Application Crashing Events". I have attached a PDF with the details, When I saw this I started thinking maybe there was a Windows issue. I have followed the instructions to check the ntdll.dll file, but the LrC crash still occurs. I have checked and double checked the Windows Event Viewer and the only time I see this error is when Lightroom Classic crashes. Everything thing else I do on my computer works fine. 

Thanks,

This probably should have started in Discussions. Feel free to move it.

Hi there, we're sorry about the trouble due to the crash. Do you know if you installed a Windows update recently or anything else that might have changed? Do you have any external drives connected to the computer? If yes, please try removing that and use Lightroom Classic to check if it makes a difference. 

You can also check a similar discussion here: https://adobe.ly/3NJqbcE

Thanks,

I am not aware of a recent Windows update. I have disconnected all of my external drives and the crashing keeps happening. I checked the linked discussion. My problem sounds similar but for me Lightroom Classic always cfashes in 2 - 3 minuyes. There is no chance to submit a crash report. I have dleted my LR preferences and restarted and the crashes still happen. I have disconnected my second monitor so I only have one monitor and the problem still occurs.

ntdll.dll issue in event viewer

This appears in the discussions from time to time. The members having it basically have not given feedback back on if they solved it. So a bit at a quandary as to if any advise helps. but basically an issue in the Windows OS .Net Framework.

• You may want to search the Internet on "ntdll.dll event error" or something to that effect.
• You may want to see if you bring up Windows Update, and click on Check for Updates, if that will trigger a re-install of .Net Framework
• You may want to use the Internet to download a copy of the .Net Framwork Repair Tool

[AHunt]

Thanks for the response.  I searched the internet on "ntdll.dll event error" and several similar searches. I have performed an System File Scan and all looked OK. I ran the .Net Framework Repair tool and no luck. I reinstalled .Net Framework and that had no effect. 

As I mentioned, if I reinstall LrC 13.5.1, the issue does not happen. If I have LrC ver 14.0 or 14.1 installed the issue occurs. I have been unable to find this issue with any other applications.

Once this is resolved, I'll be sure to report here as to what fixes it. Fingers crossed!

[AHunt]

Last night I installed Lightroom Classic 14.0 to see if the problem occurred there. It did. This morning I reinstalled the current version and tried again. It crashed but this time it gave me a chance to submit an error report which I did.

I am going to copy the saved catalog from the Old Lightroom Catalogs folder created when LrC converted my catalog for verion 14 and see what happens if I convert again and try Lightroom. I'll report the results.

[AHunt]

I copied the Lightroom Classic Ver 13.5.1 catalog backup that was made automatically before v14 converted my catalog. I placed the copy in a folder and copied in the Previews.lrdata, helper.lrdata, and lrcat-data files from the crashing v14 catalog.  I will refer to this copy as RECOVERED. When I opened the RECOVERED catalog, Lightroom coverted it to ver 14.01 as expected. I then opened the RECOVERED catalog and worked in it for 30 minutes with no crashes. I then renamed the RECOVERED catalog and reinstated my original preferences I saved before resetting them. I have been working in the RECOVERED catalog for the last hour, though it has been slow. But no crashes. 

I am not sure what this tells me. If I start using my RECOVERED catalog, I i will have lost all work since October 14, so this is not a solution. 

Any help is welcome.

My final way to get past this problem was to restore my most recent backup from before the problem and then redo work I had done since the backup. Fortunately it wasn't a whole lot. 

I don't consider this resolved.

Once the problem occurred it was easily repeatable - it happened everytime.

• After LrC crashed the Windows System Event Viewer always showed an Application Error with exception code c0000374
• The AppName was Lightroom.exe
• Exception c0000374 indicates "heap corruption" - essentially it means someone corrupted the memory for module ntdll.dll
• This occurs with no other application
• I ran various tasks to analyze ntdll.dll and found no errors.
• I reinstalled ntdll.dll and it did not correct the problem

All of this leads me to believe that Lightroom is corrupting the heap. If Adobe would like to look into this further, I still have the bad catalog and would be glad to provide assistance from my end.

I am having the same problem on Win11 and Lightroom Classic 14.0.1 with the Ntdll.dll file that crashes while in develop mode. Any new suggestions to fix this problem?

[danielh34843842]

I also have the same problem only with LrC 14.0.1...unusable due to crashes every few minutes. LrC worked fine before that version update. I hope Adobe gets a fix out very soon!

[AHunt]

When I first experienced this, restoring a LrC catalog backup from several days earlier got around the problem, but that is not ideal. That was about three weeks ago.

Yesterday I experienced another of these crashes. I was in Develop module but I don't remember exactly what I was doing. LrC seemed to freeze and then it just "went away". It did not display the "Crash Report" window so I was not able to send a crash report. I did save the error information from the Windows Event Viewer (It is attached). As stated before, this is only a problem with Lightroom Classic. No other applications experience this. 

Thanks,

I've sent a note to the team regarding the MS ntdll.dll crash and included this thread and another. 
https://community.adobe.com/t5/lightroom-classic-discussions/lr-classic-crashing-when-i-try-to-do-th... 

If they have a solution I will post it back. 

[AHunt]

Thanks, Rikk. I'll be glad to assist if needed.

Was having similar issues - LRC was crashing to desktop when switiching between images within Develop Module. Just downloaded and ran the .Net Framwork Repair Tool which made some repairs, followed by a Windows Update to reinstall .NetFramework. This seems to have fixed the problem (fingers crossed) and am back to working on images.

[AHunt]

Jack - after you ran the ,Net Framework Repair Tool, did you have a Windows Update that needed to be appliaed or were you able to force Windows to update and reinstall .Net Framework? I ask because I ran the .Net Framework Repair Tool but Windows was already up-to-date.

Thanks,

I am having the same problem on Win11 and Adobe Rush 2.10 Build 30. Opens up and crashes withing 30-60 seconds. Windows event viewer states "Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll"

Any new suggestions to fix this problem?

I have had Adobe support on my PC for about 3-4 hours so far with no luck.

[josh_2288]

To add some extra context I just bought a new Lenovo 9i Pro and also bought a new Dell XPS 14 and both PCs have the issues after setting them up.

My old laptop which is about 5 years old and my wifes laptop which is about 3 years old both run Adobe Rush on them just fine.

[josh_2288]

After spending 6+ hours with Adobe Support and getting to a Sernior Level support person they basically told me Adobe doesn't support the Intel Ultra processors yet. I had to returned the PC and buy something on the prior version processors. Works perfect on my new (older processor) PC.

[skyrunr]

Did you get anywhere with Adobe support?  I'm having this issue and the .net issue did not help.  I can only go through 4-5 images before it crashes.  I can't believe more users aren't having this issue.

[skyrunr]

After quite a bit of tinkering and testing, exporting the catalog as a new catalog seems to have resolved the ntdll.dll crashing issue!  I can now hold down the arrow key and pan through the entire catalog without crashing.  It used to crash around 10-15 clicks.  Even zooming in and out every 5-6 videos too.  I hope this helps someone.

I've been using Lightroom religiously since it came out. In the last week I ran some updates on my computer, updating Windows and applications. There were nVidia driver updates as well. Lightroom seemed much faster after the updates. I could find and tag faces in the face detection faster than I ever had. It was great -- until it started crashing.

Now I can't run Lightroom anymore -- it crashes within a few minutes of opening with the ntdll.dll error.

• Rolled back the nVidia update.
• Disabled the GPU in Lightroom. 
• Ran the dot net tool, no problems.
• Uninstalled dot net 6, installed dot net 9. Same behavior.
• sfc /scannow no problems. No pending updates. 
• Tried exporting as catalog but Lightroom crashes before it completes the export.

I use Lightroom for my personal photos, for business, and my local camera club both for teaching and competition. This is situation is devastating.

Recent Windows Update

[skyrunr]

That sounds awfully frustrating!  How large and old is the catalog?  Did you run optimize catalog before the export?  If you're running any AV software try uninstalling it.  I suspect that some of the issue has to do with Windows shadowcopy, permissions, or file compression.  It sounds like Adobe needs to look into generating more useful error reports for crashes ASAP. 

TIP  Try install Lightroom non-classic for navigating and culling/ranking images more efficiently.  It now has a local folders option.  It is clunky in comparison, but might provide you with some sanity.

I restored a copy of my Lightroom catalog from early November. Got my missing photos reimported, matched up faces in the family Thanksgiving pictures, got my cloud photos synchronized, got my published SmugMug photos back in sync.

Everything seemed to be going well with no crashes. Then I re-opened a folder that I remembered had ! exclamation marks on a bunch of photos. These photos said unable to save the metadata on the files, there was some sort of problem. I save my RAW photos as DNG and the save the metadata from Lightroom in the files, so I selected one of the photos and clicked [CTRL]S to save the metadata and see if the problem is resolved.

Lightroom immediately crashed without a crash report but the dreaded NTDLL.DLL error in my event log.

Since crashing, Lightroom crashes on load. I open Lightroom, and just wait 30 seconds and then it crashes.

One very interesting thing:

If I disconnect the network and open Lightroom there are no crashes. I can be in Lightroom for a long time. No crash. No pause, no errors. But as soon as I plug in the network -- 10-30 seconds later Lightroom crashes.

I have removed the SmugMug plugin, paused the Adobe cloud sync. Still crashes. I'm not sure what other network or online component is causing the crash.
