For all VST plugins that didnt work on my macbook pro (the new 16 inch) is used the xattr command in Terminal:
xattr -d com.apple.quarantine
after the “/” drag your plugin that doesnt work from finder into Terminal, to get the complete adres.
So for me it was:
xattr -d com.apple.quarantine /Library/Audio/Plug-Ins/VST/Ozone\ 8.vst
In my case i had to do everything from Izotope, Vengeance and some freeware like FreeClip (get it if you never heard of that last one).
After that i could re-activate the plugins in CB 
Works perfect until now.
