Catalina/InDesign 2020 AD4ServiceManager needed to install the legacy Java SE 6 runtime

Hello! Ever since loading Catalina (A big mistake—I usually wait 6 months but approved the new system w/o realizing what it was!) InDesign 2020 gives me the error then takes 3-4 minutes to load afterwards. With multiple projects all done in ID, that's a lot of minutes to wait ever day...
I've gone through and uninstalled Creative Cloud, and Adobe apps, ran Adobe's Creative Cloud Cleaner and used Clean My Mac to delete all older Adobe files, but I still get the error. I've uploaded old and new Java as well to no avail.
Any thoughts? Thanks!
