Just picked this up and there’s a major problem when using Mojave (latest version) and Live 11 (latest version).
If I have an instance (not on the track I’m freezing) of Midi Guitar anywhere in my session, anytime I try to freeze any track in the project Live Crashes. Doesn’t recover with time, just hangs forever. If I delete the instance, the session/freezing goes back to normal with no crashes.
