Cubase 10.5.20 crashes randomly on Mac

Tnx Martin. When google-ing this it seems to have to do with the app that makes crash reports possible. Thats a funny twist. But it doesnt explain why cubase 9.5 (working on 9.5 again) does not crash if its a OS issue instead of a cubase issue. Or is that a to simplistic way of thinking?

And do you maby also know what is causing the extreemly poor audio performance in 10.5 and hoe to fix that?
