Lightroom Classic Crashing

Hi!

Recently, Lightroom Classic has been unexpectedly crashing multiple times even when I close and restart the program. It pops up this error message:

"Lightroom encountered an error when reading from its preview cache and needs to quit"

I tried a workaround that was posted here, Lightroom error on preview cache or displays gray thumbnails. While it worked for a bit, the issue is back.

Anyone know what is causing this issue and what fixes it?

Thanks!

This may be the solving for your problem.

Check if you are using any antivirus protection that prevents against crypto lockers activated.

For example, Windows 10 have this function under security settings and if our pictures or the lightroom catalogue is under the current running profile this files or folders will be protected the antivirus software.

Turn of this and try to run Lightroom again.

Alright, thanks so much. Looks like I will have to wait to do so since I do not have an external HD at the moment.

No external HD, that probably also means you don't have a backup of your catalog or photos on another disk. If that's so, then I would remedy that situation and get an external HD immediately. Backups to a different physical disk are mandatory, not optional. A word to the wise, you know...

Yeah, I don't have an external backup of the catalog at the moment. Instead, I just have the images that I do need backed in dropbox. I will have to eventually invest in an external hard drive soon.

My laptops hard drive has 722Gb available out of 1TB, which makes me concern that there's so much space left, yet, lightroom is being a pain.

If you try the solution and it works for a while and the problem comes back, then you have a malfunctioning hard disk. A temporary solution might be to place the catalog file on a different hard disk, but really you ought to consider replacing the hard disk that the catalog is on now.

I never had this problem since I've had Lightroom installed on my laptop since March, the problem only recently started this week. My laptop is also just 6 months old, which is odd if the hard drive is malfunctioning.

"New" computers have been known to develop faults. (I know two friends with problem Macs recently!)

Sectors on a Hard-drive can have errors that only become obvious when the OS tries to read/write to those faulty sectors.

So, yes, as the Preview cache is having problems reading/writing, I agree with dj_paige​ above in Post#2.

Regards. My System: Windows-11, Lightroom-Classic 15.1.1, Photoshop 27.3.1, ACR 18.1.1, Lightroom 9.0, Lr-iOS 10.4.0, Bridge 16.0.2 .

Can you upload a screen shot of your Lightroom folder? It should be in your Pictures folder....

Also can you go into Preferences > Performance and Purge the cache?
