'Cubase has stopped working'

When I load a project it begins to load then crashes saying ‘Cubase has stopped working’.

I have tried loading older tracks that are currently released and its the same thing.

I can create a new project but any saved project just crashes.

I’m currently using the updated 8.5 version running on 32gig ram, i7-6700, 64bit.

Worrying me. I was thinking should I reinstall the program?

If anyone can tell me what’s happening here it would be much appreciated!!
