"Serious Graphic Card Error"

i’ve suddenly got this error message, while being idle with an open project:

my graphic card is Nvidia Geforce 3070, and the cubase version is Cubase Pro 11

i also have a dump file but the forum won’t let me attach it

what could be the problem?

You’re okay’d to upload zip and upload your crash log file

ok, here it is -
Cubase 64bit 2021.1.10 (189.0 KB)

also, when i reopened the program it gave me this message, maybe it provides additional useful info-
