I got this error in every 2020 unity version.
I tried putting D3Dcompiler_47.dll file in C:\Program Files\Unity\Hub\Editor\Editor\Data\Tools it works but then 2 blank erros appear in the console which don’t let me hit play button.
I have the same problem, managed to solve?
I also have it, more and more often it seems, never had it before 2020.1,
Tried the tdrDelay register method and the firewall exception method, none of them worked !
Come on Unity, it is not a matter of how many geometry the scene have, I have the issue with a small scene, and never had it with much bigger ones on previous versions !
I have the issue as well in 2020.1.16. TdrDelay and firewall exceptions doesn’t work here either!
Had this problem with 2020.2.7f1 release (was not happening with the 2019 LTS version)
I was using NVidia 460.89 drivers with the 2020.1, updated to current 461.72 (as of this day) and it seemed to stop
