Thunderbolt 3 and legacy FireWire on MacBookPro

Hello,

I'm connecting a Phase One digital back (professional photographic camera) to my MacBook Pro 15 2018 (updated software) through a FireWire cable 800 to Apple adaptor to Thunderbolt 2 to Apple adaptor to Thunderbolt 3. Everything worked fine till today. I've tested the same connection system on a friend's MacBook and it works fine.

What happens now on my Mac is that once connected to my Mac the fan suddenly starts at maximum speed, screen goes ⅓ black and it restart giving subsequently the attached report.

Any ideas?
