Hello, hope someone could throw some light on this, I never had any problem with Kontakt pre 7 in years, some libraries have forced me to go to v7, but as I tell in the title, I cannot make the plugin work in at least 7 different version instances of 7 I tried, (for each version wiped all previous data via AppCleaner and then deep searching with EasyFind for .bom .plist, receipts, preferences, hidden files, etc so as to leave not a single file referencing anything related to Kontakt)-
In all cases the result is this: the VST3 is seen at Cubase 15 bootup, the plugin manager log says it has been scanned and validated. But it will not show as an option in the Instrument column on the right window nor if I try to instantiate manually-
Reaper and Studio One 6.5.2 load the VST3 normally.

I cannot go to version 8 as I am on macOS Bigsur 11.7.10 which according to Steinberg´s web accepts up to version 7.8.1 (although I got V7.10.1 to load as standalone and AU in Logic, not VST3 in any case)-

I have done Permission Reset and Codesigned each of the versions with no difference.

Thank you all.
