Would suggest you to create a new catalog then, go to File menu> Import from another catalog> choose that particular catalog to be imported from and check if you are able to import.
If not, it could be possible that the catalog has got corrupted.
Thankyou ! That appears to be working. Im just confused as to why it suddenly stopped working along with another catalog im working on.
Thank you again !
The Previews might have got corrupted and that is why when you imported it in a new catalog it appears to be working again as the previews would have been recreated.
I see, I wonder what might have caused that to happen. It appears two of my working files that I worked on today have been affected.
Not ideal by any means, but I am glad that theres an easy way to work around it !
Thank you again for your help, you have no idea how much stress you have saved me, I truly appreciate it.
Glad to help
