I reboot computer (Win11) start Gig Performer (5.1.4) and load empty gig
I insert a couple VST instruments (e.g. Lounge Lizard, VB3-II) and make sure all is working fine.
I insert an Arturia V Collection instrument that is NOT a “V4” version and that is working fine.
THEN I insert an Arturia V Collection instrument that is a “V4” version (e.g. Mini V4, CS-80 V4) and “poof!”… Gig Performer disappears completely.
MORE INFO:
It is the V4 version THAT IS ALSO VST3 that causes the issue.
The V4 version that is VST (not VST3) works fine.
So for now I know not to use VST3, and only use regular VST, of the V4 versions.
