I have just upgraded to LR Classic V. 10 and notice that as well as the new LR Catalog 2.2 V10 and 2.2 (for LR 9), I also have a 'Corrupt Catalog from May 2020, 3.2GB in size. Around that time my PC needed major surgery, eventually the problem was traced to bad RAM. The upshot was that I reinstalled Windows 10 and LR Classic V.9.x and successfully reinstalled a backed up version of my April 2020 Catalog. I also got rid of loads of previews I had accumulated since 2012, and everything has been running fine since May 2020. Presumably it is now safe to delete the 'Corrupt Catalog dated May 2020? I attach a screenshot which shows the breakdown of my LR Master Catalog.
