Have you tried to purge the cache yet? If not the settings are here: Preferences>Performance>Purge Cache

The Camera Raw cache contains the Develop previews, and purging it will not fix this problem.

The error message refers to the Library previews, which reside in the same folder as the Lightroom catalog.

It displays as a folder on Windows, and, I believe, as a file on a Mac. It has the same name as the catalog, and ends with  Previews.lrdata [Catalog name] Previews.lrdata

​Deleting it should fix the problem.

If the same problem keeps happening, then your hard disk is malfunctioning and you probably ought to replace it.

You have some type of hardware problem. In a newer post you said you replaced the SSD in your system. Is that the only drive in your computer?

Is that SSD where the catalog is stored? The Previews Cache folder is stored in a subfolder in the same folder the catalog is stored in.

If that is not on the SSD that you replaced then that could be the problem. The drive that holds the catalog file and the preview files is going bad.

If the SSD is the only drive in your system then it is more than likely a RAM problem or possibly the CPU is overheating and causing bad writes to the drive.

I have replaced the hardrive (SSD drive) and I'm still experiencing the same cache problem - the problem is getting worse the more I use Lightroom (I've been importing pictures and within 5 minutes Lightroom closes the application with the same cache notice.

Well, some very basic questions:

  1. Is the disk you replaced the disk where the previews are stored?
  2. How did you restore the LR catalog and previews? (Please give step-by-step description)
  3. Have you run diagnostics on this disk?

I know this is an old thread, but I thought I would post my solution in case anyone else has this same issue. I was having this same issue even after deleting the folder multiple times. I guess a while back I locked down some specific directories for protection through "Controlled folder access" settings in Windows 10. You can either disable this protection by turning it off or you can allow the Lightroom.exe file through controlled folder access. These settings can all be found if you press your start button and type "Ransomware Protection". It should pop up as an option.
