If you look at WinDbg it will have two "BlackBoxed" areas. Sometimes those will indicate a device which could be involved.
It does appear, from your comments, an ATI video card is involved. Possibly the driver being used needs to be updated beyond what you might get from Dell.
I could also be related to a Catalyst control center or whatever utilities that card would use.

@Saltgrass So much research into this, I'm quite good on decrypting the debug files now, but nothing of use there.
A newer Insider version of 20H1 is out (18885), installed and fixed the problem. For now, just left it running with the default Radeon driver from Intel (18.2.2 iirc). I will update after a few days to latest ATI generic package, driver-only first (18.4.3 was just released last week), and add the Control Center later on if no green screen.
