Cubase 10 freezes and hangs.

Cubase 10.3 on Mac randomly crashes with a spinning multi-coloured ball. After this happens, I have to Force Quit, then it refuses to open that version of a project again. I can’t see any way of getting a crash dump or finding what’s wrong. I have a suspicion about Eventide Plugins, but without any data, I can’t know for sure. Pretty annoying.

I’ve had a perennial problem with NI Komplete Kontrol so have moved that to the bin. it’s unusable for me.

ARA2 stability is rubbish, Melodyne pleases itself if it turns up on tracks, after being edited and saved. Sometimes it’s there showing up with the edits, sometimes it’s not. For me, this is the worst and buggiest version of Cubase I’ve ever had and that’s been over 30 years. I don’t know if it’s Cubase or/ and plugin issues and ARA2 problems.

Is there anyone with similar issues? can anyone help with where to turn?
