P: keeps crashing on startup - 9.4 also 9.3 also 9.2.1

Report · Oct 04, 2020

Dear developers,

PLEASE make a troubleshooting article in the official support articles for Lightroom Classic, for the startup crashing problem appearing constantly.

The Lightroom Classic starts, it shows the pictures from the library, then it pops up the error reporting window - 0xc0000005 error.

I faced this already 4 times during a short time period of 3 months.

Everytime I did more hours of troubleshooting and googling what can cause this problem.

I started with GPU drivers, update, rollback, delete, clean, install. No result.

Then I went for Windows updates, installing the latest updates, then uninstall up to the last day, when LR CC worked. No result.

Then I did sfc /scannow system integrity check, it did not find any problems.

At the end I found out, that:

The ADOBE CREATIVE CLOUD app is the reason. It is constantly getting corrupted.

Even it is corrupted, the app runs, does not show any problems, but after reinstalling it, the problem is solved with Lightroom. Interesting, that other Adobe apps are working well, just the Lightroom Classic is gettin f*cked by the Creative Cloud app corruption.

So, the problem is not GPU related, it is not GPU driver related, it is not hardware related, it is not software related, it is not windows update related. Just the self-manager, the Adobe Creative Cloud app.

Please, do a support article about this, so people are not getting angry as me, if this happens.

Thanks for submitting the crash log. I've asked engineering to take a look at it. We will update this thread with any information.

@Rick

Thank you too for the support.

I have sent multiple crash logs with various message, the last one was a bit angry one, after a long time of troubleshooting without success, sorry about that.

At the end I found out, that the Adobe Creative Cloud app was corrupted - again. Do not know, what leads there, so it is being corrupted, but happened more times already.

After I reinstalled the Creative Cloud app, problem got fixed.

Here's a fix you might try. It has worked for me every time I've tried it, including today. I have no idea why it works, but it does. I'm on a Windows 10 computer. I'm not sure if it works for Mac.

Make sure Lightroom is closed.
Using Windows Explorer, rename the folder where all of your photos are stored on your hard drive. You don't need to rename the folder where your Lightroom catalog is stored.
- For example, if all of your photos are stored in a folder called "Pictures," rename that folder "Pictures_disabled" or something similar. Anything other than "Pictures" will work.
- If you have photos stored in many different locations, you may need to rename each of the main folders.
- Also, if all of your photos are stored on one hard drive and it's not your C: drive, you can rename the whole hard drive. If it's the C: drive, you cannot rename it because that's where Windows is stored.
Now that you've renamed the location of your photos, open Lightroom the normal way. It will open and work normally with the exception that it has lost track of your photos. This is expected because you no longer have a "Pictures" folder, for example.
After it has fully opened, close Lightroom and make a backup -- just in case.
After Lightroom has closed, rename any folders or hard drives back to their original names by removing "_disabled" from their names.
Once that is done, open Lightroom again. It will work now without crashing.

If anyone at Adobe can explain why this works, I'd be glad to hear it. I hope this works as reliably for you as it does for me. Good luck and let us know how it goes.
