New problems after updating to 14.2 - High disk usage, export doesn't work

[PagiArt]

After updating to 14.2 I have new problems with Lightroom Classic. Again! This time Lightroom causes continuous high disk usage, even though I am not doing anything. What's more export isn't working! When I try to do export, nothing happens. How to get Lightroom to work again? 

And it's not catalog drive, it's my photo storage.

Hey, @PagiArt. Welcome to the Lightroom Classic Community. . I'll need more info to help you figure this out. Please share the system info from Lightroom from Help > System info > Copy and paste into a text document > Upload and attach here. 

Have you recently updated the OS? If you're on Lightroom - is Sync enabled? 

As primary steps, try this:

• Unplug additional displays & use only one by default.
• Monitor the Task manager for any unexpected read-and-write operations. 
• Go to Edit > Preferences > Performance > Use Graphics Processor > Set it off if it is on Custom or Auto. If this shows any differences, please check this article to troubleshoot further: https://adobe.ly/3uYiJo4.
• Check this detailed response from our Expert: https://adobe.ly/4g6Cb4j

Let me know how it goes. Thanks!

It looks like that after I waited for about 30-40 minutes, Lightroom stopped doing whatever it was doing on the disk and after that it started working normally. It happened right after the latest update. So Adobe, please, if Lightroom has something to process after the update, just add an corresponding progress bar, so users know that they should wait for any process to finish.

I am having the same issue. The export starts, but after exporting a photo or two, it stops and the catalog stops responding.

It worked after setting Graphics processor to Auto, but I do not want to use the GPU to export photos, the CPU can export the photos a lot faster.

Is there any workaround?

@manzurfahim Yes, there's a workaround.

Goto the preferences and set the option Use Graphic Processor to Custom. Then you can disable the GPU usage for export.

Thank you for the reply. But this is my setting. Custom and GPU export off. But it does not work. It exports one or two files, then the catalog stops responding. Only when I set it to Auto, or enable GPU export, then it works.

I tried upgrading drivers, rebooting the system. Same issue.

GPU - RTX 4060 Ti

Make sure that you are using the recent Studio version of the driver, not the Game Ready version.

If you have buldin a CPU with an internal graphic processor disable the processor internal graphic card. To disable  use the Device Manager on Windows. In the Device Manager, right-click the card's name and choose Disable.

If this doesn't help, try to reset 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:

If this all doesn't help, 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.

Intel GPU was already disabled. Studio drivers didn't help either.

But I managed to fix the issue. NVIDIA GPUs were having some black screen issues with the latest drivers, so I uninstalled the new driver series (572.xx), and went back to 566.xx version. Fixed the issue. No more problems exporting with CPU.

Thank you for all your help and prompt reply, much appreciated.

[AxelMatt]

I've read about such black screen problems. But only with Game Ready version of the driver and I'm using already the Studio driver 572.60 with a RTX 3060 on a Win 11 24H2 system without any issues.

But the main thing is that you have found a solution to your problem.
