Flashing black screen on launch, can't interact with game

Problem:

Upon launch of the game the screen goes into various shades of black, it looks a bit flashing. Nothing else happens visually, but in the background the game is actually running. Alt-Tab or other Windows interactions have seemingly no impact, at least you can't see them.

Solution:

On your TV (might not happen with computer monitors) go to HDMI mode settings and make sure you don't have the highest setting enabled there (HDMI 2.1) turn it one notch down (HDMI 2.0).

On Hisense it's called "Enhanced Pro" that is causing problems, I have to turn it to just "Enhanced Format". On Samsung the offending setting might be called "Input Signal Plus", or on LG "DMI ULTRA HD Deep Color" or with Sony or TCL simply "Enhanced" something.

Background:

I only had this happen before in one game or rather the demo of Hell is Us. It seems the game is trying to set a certain video setting combination that makes the TV switch back and forth, maybe related to VRR.

For what it's worth my TV is a Hisense 65U78N running at 120hz in 4k.

Hope this gets fixed asap so I don't have to change my TV settings just for this game, and hope this helps someone else!
