P: v14.5 Lightroom has encountered problems reading this photo | Round circle ‘!’ warning on Images

OS: Windows 11
LrC VERSION: 14.5

A couple of days ago I upgrade to v14.5.
As for every update, I regurlay empty cache, optimise catalog, remove all previews and generate new standard ones (also, I wanted to test how was was the new option to use GPU for generating previews).
Never had a problem with this workflow.
After previews generation process was completed (1h 30m for 29.000 files, 23.000 jpegs and 6.000 raws) I got an error: for 21 RAWs the preview could not be generated. Looking in the catalog at those files, I realised they have an exclamation mark on a dark circle: this is not the missing photo mark. If I click on the exclamation mark, I see error "Lightroom has encountered problems reading this photo, you are not allowed to edit this image. "

Yet, I can still enter develop module and edit the photos without any problem: the editing history is there, I can zoom in at 100% (generating the 1:1 preview), I can change sliders, export... Everything... (PS: I do not use smart previews).

The 21 problematic photos are in different folders and have different dates.
The files can be opened by any other program, including Fast raw Viewer.

For a couple of problematic photos, I tried deleting the photos from file explorer, and the square light missing photo question mark replaced the round dark question mark.
I restored the files from three sources:
1- the original file
2- a backup from a second HD
3- a backup from Amazon Photos

In all three cases above the black round exclamation mark came back: this should prove that it's not a problem of corrupted files, I instead believe it's an issue in LrC.

Just confirming that I have that same issue, starting with LRC Vs. 14.5.1. I can edit these normally, but often the thumbnails shows the imported file, but the E and Dvlp views show the edited version. No limitation on editing, it's clearly a glitch.

Try resetting the preferences of Lightroom Classic: How to reset Lightroom Classic preferences (adobe.com)

It's recommended to backup your preferences before you reset the preferences to the default settings:

https://helpx.adobe.com/lightroom-classic/kb/preference-file-and-other-file-locations.html

Check if your system is up-to-date. Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver? If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.

Please provide a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

My System: Intel i7-8700K - 64GB RAM - NVidia Geforce RTX 3060 - Windows 11 Pro 25H2 -- LR-Classic 15 - Photoshop 27 - Nik Collection 8 - PureRAW 5 - Topaz Photo

@Sameer K this is very good news.

As both a photographer and a computer engineer, out of curiosity, may I know what the issue was? 😀

I appreciate your curiosity. As far as I can say, the issue ties back to the preview rendering pipeline via Camera Raw engine embedded in Lightroom Classic.

Thanks!

@dj_paige please stop suggesting this exclamation mark means corrupted. Yes, in general this means corrupted but it is obvious by what @Anshul_Saini has clearly stated (thanks to me being the first to report this issue, after exchanging many logs and screen recordings and photo samples) THIS IS A BUG IN THE NEW 14.5 VERSION IF LrC.

Please @Anshul_Saini I believe this thread should be kept on topic: people who randomly get on very few images the exclamation mark on dark circle due to a combination of two things:

1. A brush in a mask (not all brushes, though)

2. GPU enables for preview

By removing either one, the ! disappears.

By the way, the images showing the ! ARE NOT actually corrupted: you can keep on editing them.

This thread is becoming a mess...

@Anshul_Saini is there any news from the development team? Thanks for your support.

Hey, @Giovanni Stoto. The team has identified the issue and the fix will be released soon. We will announce a fix as soon as it is out.

Thanks!

Yes, this is the exclamation point you get when your file is corrupted. Please try restoring a backup of the file, as I suggested earlier.

Although it might be a bug as well, Adobe is investigating.

I am using the lastest version of Lightroom classic 14.5.1. Started recently, some photos start showing "lightroom has encountered problems reading this photo" icon and message. It seems that photos with more editing steps/history are more likely to have this issue.

I searched the forum. They all said that disk might be the cause, but it cannot explain why it only happens on a few pictures and pictures of more editing steps.

Plus, although the message indicates that I "will not be able to make adjustments to this photo", in fact, I still can edit and export the photo. The preview might have the issue sometimes so it is annoying.

I wonder if this is a known issue.

There could be a similar report, https://community.adobe.com/t5/lightroom-classic-bugs/p-v14-5-lightroom-has-encountered-problems-reading-this-photo-round-circle-warning-on-images/idi-p/15470236

I was editing photos on Sept 1st and didn't finish so I was working on them on Sept 5th and kept getting an exclamation point on my photos that I tried adding a mask and typically the mask wouldn't even do anything.

If I tried the mask first and then add a preset, it would add the exclamation point to the photo.

I noticed that LRC recently updated to 14.5.1 so I tried going back 1 and 2 versions but that didn't help.

I tried using default masks incase the ones I purchased got corrupted and still have the issue.

Anyone know what could be happening?

Hi @Sarah_Kanable5742, welcome to the community!

Could you share a bit more about the type of masks you're creating? Are they AI masks? If you can include a screenshot of what you're seeing on your end, that would be super helpful.

If this issue pops up when using AI masks and Lightroom Classic keeps asking you to update them, there’s a quick fix you can try. With the app closed, head to your catalog’s folder and move the .lrcat-data file out of it. Lightroom Classic will regenerate that file the next time you launch it. Since that file stores AI mask data, this can often clear up the issue. Once it’s regenerated, try updating the masks again and see if the prompt still appears.

Let me know how it goes or if you have any questions!

You misunderstood. The GPU is disabled automaticaly by the error, not by me, as you can see in the screenshot.

I understand, @andre29143016m9nk. What you’re seeing is slightly different from @8423554 Stoto’s repro, where disabling Use GPU for Preview Generation manually worked as a workaround for him. For you, the problem also occurs in 14.4 with Camera Raw 17.4, and Lightroom is auto-disabling the GPU mid-session.

I’ve documented and shared your exact repro steps with the product team:

GPU = Auto (working normally)
Apply AI mask > mask creation fails > image flagged with “!”
Preferences now show GPU = Off (disabled automatically)

The team has these details attached to the existing bug so they can investigate why the GPU disconnect is happening differently on your system.

I’ll keep this thread updated as soon as I hear more from engineering.

Best,

Anshul Saini

@Anshul_Saini any news here?

This post is getting a little messy as other Expert users here are asking for logs or system info trying to help but making more ci fusion.

I am in Indonesia now shooting, I'll be back in 15 days with no less than 5.000 pics to cull and lots of edits to do: I hope that by then I new version fixing this bug will be released.

I want to be clear on this, as a long time IT expert: this issue is not directly due to hardware or software issue on each person's computer, given the issue appeared out of the blue with the new version on LrC. Adobe has to fix this.

With years LrC performance and stability has been shaky: one version is problematic, two version are ok, than buggy then ok then very slow UI performance etc etc. And all we are told is to upgrade GPU drivers or that we don't have enough vRAM or that our drives are slow etc etc

We do not need more AI functionalities, we don't need more masks or features: we want a fast, reliable and stable software to edit our photos. Whoever needs more than what typically LrC provides (layers, sky replacement etc) will use Photoshop.

Just give us a software that works.

Thanks

Hi @Giovanni Stoto, and everyone following,

Thanks for sharing the logs, @andre29143016m9nk, via DM. I’ve forwarded it to the product team. As you confirmed, disabling Use GPU for Preview Generation prevents the error from appearing. Based on this, the Lightroom Classic team and the Camera Raw team have logged a bug, and both teams are actively investigating a fix.

At this point:

The issue is confirmed as a product bug, not specific to individual hardware/software setups.
There isn’t an ETA yet, but engineering is tracking it as a priority.
I’ll update this thread if further details are needed, or if there are interim workarounds beyond what’s already shared.

We appreciate your patience and collaboration while the teams work on a resolution.

Best,

Anshul Saini
