Game closes itself after around 30 seconds

Hello y'all

After some days, or even a week, I wanted to start the game again and create a new character.
I can't even create a new character; the game freezes for 1-2 seconds and then closes without any message.

7800X3D
Asus Pro Art 4080 Super
Asus Tuf Gaming B650 Mainboard
32 GB Ram Corsair Dominator
Any other game works.

NVIDIA's latest drivers are also installed.

Does anyone have any idea what I can do?

PM: I aslo reinstalled the game already, still the same issue.

So I figured out that if I am in a Discord channel and share my screen—not the game, just the screen—then I can play the game. If I am not in a Discord channel and share my screen, the game only works for 30 seconds.

What the hell?

Can someone confirm, please?
