Cubase quits unexpectedly

Running Sierra 10.12.6. When I open Cubase it quits before loading completely every time. When I restart it all is ok - for a while. I start recording whether its using a built-in template or one of my own - then bam, Cubase 10 Pro suddenly quits completely. I mean its gone. Not frozen, but completely gone.
I’m assuming its a VST issue. But it happens whether I have any open or not. Is there a way to determine which vst’s are potentially the issue?


Is there any crash dump file created?
