    Unable to open catalog on Lightroom Classic CC after upgrading OS


      I have finally upgraded my computer's OS and reloaded Lightroom onto the PC.


      I was hoping to just take one of the backup catalog files and getting Lightroom working, but I keep getting the error "Assertion Failed" every time it opens the catalog and a crash report being sent to Adobe, with no suggested fix.The version of Lightroom was also the same from one machine to the other.


      Is there anything else I can do, or do I face the cumbersome task of importing photos into a new catalog?




      System info:

      Original OS: Win8

      New OS: Win 10 Pro 1709


      Photos for my catalogs are in the exact same location, just a new OS installed.
