I upgraded to Lightroom 11.0.1 and now it isn't loading.

[katiej86022461]

I am on a Mac Book Pro / Catalina Version 10.15.7 

I update my Lightroom to 11 and now it says it is 11.0.1 and my collections are gone as well as all my filters in images ( flags, colors, stars, etc.) . I did a backup before the inital update to 11. This beyond frustrting and I am in the middle of a project and need this fixed asap! Is there anyone from Adobe that can help???

As you did a backup, try what happens if you replace your catalog with that backup copy.

Did you import the photos into a new LrC 11 catalog? Or did you upgrade the previous catalog to LrC 11?
