Try unzipping a recent backup copy of your catalog file, and see if that file will open in LrC. Double-click on the unzipped catalog file in your operating system (Windows Explorer or Mac Finder) to open the file.

I think it worked! 
Going to try to work to see if everything is OK.
Thanks

you can also try to reset the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com)

It's recommended to backup your preferences before you reset the preferences to the default settings:
