I keep having crashing with Groove Agent 5 while in Cubase 12 pro. See my thread here:
“A serious problem has occurred…” often in Groove Agent 5 - Cubase - Steinberg Forums
It’s interesting that it is happening on both Mac and PC. And the crashes seem to only occur while running in Cubase 12, not in standalone, or even when I tried it in Pro Tools (Note I later was able to crash Pro Tools while in Groove Agent 5). Weird.
