Groove Agent 4 crashing even in standalone

So I’ve tried reinstalling but to not avail. GA4 crashes any Cubase or ABleton project as soon as I try to load it. It also crashes when I open it in standalone - it has the splash screen, goes through the motions, gets to Initializing: Groove Agent 4.2.40, then nothing.

I’ve had problem with this program since day one - it’s buggy as hell. For the past 2 years I’ve not been able to access any of my installed expansions packs - it only remembers the last installed pack. Library manager shows they are there and installed and installed correctly correctly, but they simply do not show in the GA GUI or in Mediabay.

Now though, I cant even open it at all.
