I've been having this issue with my old and new MBP. It must be linked to an application but I can't for the life of me figure out what. I'd initially thought Adobe CC but appears not.

I've spent hours speaking with Apple support but had no joy.
Here's a diagnostics report from recent crash. If anyone can shed any light on this I'd be forever in your debt.
I've had to post the report externally due to the character limit here:
