Plugins hanging and having to force quit Cubase 10.5

So mony Plugins cause Cubase 10.5 to hang when opening them, resulting in having to do a forced quit of Cubase and go through the process again. Ozone 9 advanced doesnt even want to work after opening on my 2 buss.
Fabfilter Pro Q3 works when Cubase allows it to… So frustrating how Steinberg can always get this wrong. No wonder people jumping ship, I dont blame them.
