Guaranteed Crashes when loading if audio is in the session

Hi everyone, would really appreciate some help on this problem which has been present for over a month and I’ve finally found the cause.

Cubase session loads until the very end of the progress bar then crashes and presents this problem report below.

I’ve tried everything and I’ve discovered if there is ANY audio in the session it crashes. So if I delete any audio from the destination folder, it can’t find the audio but then also loads perfectly fine. I’ve tried copying any imported audio to project and not doing that to see if that made a difference. I’ve tried running it off different hard drives but no luck. I’ve tested this on about 30 projects and those without audio load fine. I’ve also tried installing from scratch and trying on Cubase 10.

Any suggestions please? Big thanks!

Cubase 10.5.20
Catalina 10.15.2
