Correct answer Jim Wilde

Which version of Lightroom (Classic or "cloud based"), and what version number?

It sounds like a problem with the lock file still present, which can happen after a crash. Using File Explorer, look inside the folder that contains your catalog and see if there is a file that ends with ".lock". If it is there, delete it.....do NOT delete any file ending with ".lrcat", only delete the file ending with ".lock".

What is the version you have installed (numbers, not latest to alike)?

What is your OS?

Did you try a reboot?
