For sure a current Witcher 3 v4 -related problem.
For an AMD RX 6700 XT , driver v. 25.6.1 performance profile, on Win11 I can "reproduce" game crashes/blackscreen esp. in closed room e.g. below Novigrad/Kaer Trolde, sometime after tab out of the game, return ingame and wait for fps degradation.
I had less and random crashes on an NVIDIA RTX 3070 , diver versions 560.94 / 566.03 / 572.83 on WIn10 and the same other hardware (Ryzen 7 5800X, 32 GB RAM, NVME SSD,... ) - and not such fps degradation.
[Game version v.4.0.4., clean reinstall in between, borderless window, 1080p and dx12: Raytracing on but lowered on features like RT for shadows (OFF) - for both graphic cards, and RT for environment OFF for 6700XT, too. PowerMAX and Memtest tools run = system temps and stability is ok, other games work like all around GamePass]
