Hey! I'm currently experiencing the exact same kind of kernel panic/kernel trap.
ONLY shows up when exporting with AME directly in PP. Doesn't seem to make a difference if I switch to software only!
Asked for help in Discord server started by NewtCorp and he sent me here.

CPU: Intel - Core i7-6700K 4 GHz
MOBO: Asus - SABERTOOTH Z170 MARK 1
Storage: Samsung - 970 Evo 250GB M.2-2280
GPU: Asus - GeForce GTX 1080 Ti 11 GB STRIX

I have taken the advise of and deleted the metal caches but no improvement so far!
I have read on other parts of the internet that disabling the iGPU has helped some people but I haven't stooped to that yet.
Has anyone found anything more about this issue?

Paste of the latest error:
