The issue is now fixed with Illustrator 25.4 that is available on Creative cloud App for download. Can you please update to this version and try this out.

I am still having this issue with Illustrator. Libraries are fine in other CC applications but zoomed in view and makes it unusable. Signing out then back in to account is a temp fix but cause issues with time taken to reload fonts etc.

My CC library keeps bugging out, sometimes it previews as huge and other times and really tiny. When this happens I cannot access my assets and is incredibly annoying when working under extreme deadlines. I have updated everything and restarted. Please fix this its turning out to be more hassle than it's worth.

This is happening is PS, AI and ID

Still happening in 25.2.3. See screengrab. Things just expand or get stuck and then you can't select anything. You have to quit out application then reopen to reset it so it stops happening.
