"Lightroom encountered an error while reading its preview cache and needs to quit".

I keep getting this error randomly, sometimes when switching between Develop and Library Modules. While restarting LRC (13.31) always works, its annoying that it happens so often.

My catalog and images are on an external SSD drive with updated firmware.
Have have verified the integrity of the catalog and SSD drives
Windows 11, all updated-even did a clean re-install thinking maybe I had some other conflict
Nvidia Studio Graphic Driver updated to the latest available- turned off GPU acceleration in LRC performance settings
Plenty of memory on the graphics and computer-see system info attached
I have deleted the Previews.lrdata folder multiple times
I reset all preferences
I removed all plugins
I un-installed and re-installed Lightroom after rebuilding the operating system.
Computer firmware and Bios is up to date as well.
I built a new catalog and imported from my old one thinking maybe I had something goofy in there as well

This is a Microsoft Surface Studio II, with 32 GB of RAM, and 8GB on the graphics but I'm wondering if LRC is just pushing it to it's limits as it is an older computer. Intel Chip set: =Processor Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz, 2904 Mhz, 4 Core(s), 8 Logical Processor(s)

I finally solved this I think, Fingers crossed and a big thanks to everyone that tried to help.

I think I had a corrupt catalog that no amount of catalog integrity checking would fix. Exporting to a new catalog didnt solve it either. I had at one point imported a large number of images from a family member that was not familiar with LRC, and used other editing and scanning software, so I'm beginning to think there were some corrupt files that LRC just couldnt figure out through usual tests. I solved it by creating a brand new catalog that resides on my main PC's Local drive and re-imported all my images. Drastic I know! While I lost the editing history, I didnt lose the edits themselves and can always reset back to the orginal raw file if need be. I'm going to try one more test and put that catalog back on the external drive to see if that creates issues. (all my photos are on an external SSD) Technically it shouldnt be a problem, but I have read reports of others suggesting it not be stored on an external drive. Time will tell.

No solution I am afraid, but I have a similar problem when importing images LrC will just come up with an error and close. Spoke to Support 3 times each with a different excuse but no fix, even had one say I was low on RAM, I told him I have 96gb installed. Last one suggested it was a faulty Agkernal.dll repaired windows still same. Anyone any clues please?

"I have deleted the Previews.lrdata folder multiple times"

Try restarting your computer and then deleting the folder. LR shouldn't be running when you delete it, and in rare cases it doesn't fully terminate when you exit. It's a long shot, but to be on the safe side, just restart the computer first.

In your operating system, you will have to erase the preview cache. Lightroom Classic will rebuild it, but it will be slow scrolling around in the Lightroom Classic Library Module.

Go to the folder where your catalog is located, and delete the folder whose name ends with previews.lrdata. DO NOT DELETE ANYTHING ELSE.
