13.0.20 Does not shut down/MediaBay Error/VST's do not work

OS X Sonoma 14.3 - Just when I got Nuendo 13 working … I updated to 13.0.20 and now have to hard close upon closing app (rainbow wheel of death), MediaBay error (cannot access files) - I deleted Steinberg MediaBay Server folder from the preferences folders, Deleted/re-installed Nuendo 13, no go? I tried Safe Start Mode and disabled the third-party plug-ins…still no-go. Any ideas? PS: Nuendo 12 works perfectly fine for me.
