parallels crashing on MacBook pro 1015 15"

three VMs that run fine on newer machines all crash on Catalina on my MacBook Pro 2015 15" machine.
i7 chip, 16gb RAM, mid 2015.

They run for a few minutes, then the screen starts flashing, goes blank, changes to blue and black, then just flashes until I power the Mac down.

This is true for all three of my VMs -- a Catalina, a Windows 10 and an Ubuntu, all of which run fine on a MacBook pro 2017 13" and a MacBook pro 2019 16".
 
Ran first aid on internal and external ssd's, they're both perfect.
ssd is samsung t5, usb-c to usb connection.

would this happen because VMs were created on incompatible machines? Is that possible?

A test would be to create a new VM.
 
No, it doesn't work when I create a new VM, either. Parallels just doesn't work on this MacBook pro 2015 15".
