Thumbnails are grayed out

Lightroom Classic:

Even when deleting the previews cache, rebuilding smart cache and build standard cache nothing is working. 
Deleted Cache folder. This is a serious problem.

Which version of Windows?

Which exact version of Lightroom?

Which camera? JPG or raw files?

What are the details of drive E? Is it in power-save/sleep mode?

What do you see when you expand the E drive in the Folders panel?

It seems that your monitor profile is corrupted.

That would affefct only the thumbnails and previews?

I can still edit the photos.

That fixed it! Thank you.

How does a monitor profile become corrupted like that though?
