Hi, official 7.4 on AVL. I have a session where I can no longer add certain plugins without Ardour wrecking (it just winks out). Other plugins load ok. I had done some pitch-shift, as the only non-normal thing I do. I tried to recreate this in another session, but was unsuccessful, so something is just whack with this session. For example, if I try to add ToneLib GFX (vst2 or 3), it dies. If I add an acmt, it’s fine. Again, in my attempt to recreate in a new session, all works fine.
So this is only an issue with an existing session, but not a new one?
Could it be a conflict between plugins present in that session?
Since ToneLib GFX is non-free it would be helpful if you could provide a backtrace: https://ardour.org/debugging_ardour and yes, please post it to the bug tracker.
