12.3.1 screwed up my PT install

Everybody else here seem to have no problems upgrading to 12.3.1, but they may have have those specific plugins.

What Izotope plugins are having problems? From 12.3 to 12.3.1?

I had to move about 20-30 plugins to the unused folder.
Since working without them is not really an option for me and I am about to start working again in the studio next week I decided to revert the os to Catalina.

Why revert all the way back to Catalina (2 generations of macOS ago)? If the plugins worked in Monterey 12.3.0, wouldn't that be a better platform and position you for future releases. Looking a some of your older posts, it seems you have been having other problems upgrading from Catalina also, I know production deadlines are important so do what works for you. When time permits, you might want to do a clean install of macOS, Protools, and plugins. Migrating or "insitu" upgrades are prone to bring issues along to the new setup.
