After reading through the crash log what I realised is that all of the crashes I was experiencing in Cubase (including the control room one) were down to the surroundpanner VST that's built into Cubase.
The fix in my case was to remove the surroundpanner.vst3 file from Cubase.app/Contents/VST3. Keep a copy of it in case you decide you need it one day.
This got me thinking though - is it possible that this VST3 could be patched in the same way that Adobe software is? I have no idea.
