Black screen when loading map

Hello (sorry for my bad english) After-loading locations (Chapter 6) after the Sedo generator (do not remember the exact name) but HUD did not appear on the screen, I could not shoot, you can hear the sound of walking, but the screen is black …
In the console, a lot of errors (screenshots in attachment)

Thanks for your report. Could you please provide the hardware and software details of your PC, they are essential for troubleshooting this problem.

It looks like a problem related to misbehaving post-processing shader on some older GPUs. Could you please try proposed workarounds available here:

Report back to that thread if workarounds works for you or not. Thanks.

Problem resolved itself, I made a quick save, but when the game is loaded, there is a problem before, but when I took uploaded autosave, which was 2 minutes earlier, everything was fine.

The problem was quickly saving
