Graphic issues

I am experiencing significant graphics issues, making the game unplayable, even though I have a high-performance PC. My monitor settings are set to HDR, and the screen resolution is set to 144 Hz. However, when I launch the game, my screen suddenly becomes darker—completely different from how it looks on my PC. As soon as the game opens, the screen just turns dark, which ruins the experience entirely.

I’ve already adjusted key NVIDIA settings and changed the resolution and refresh rate in the game to lower values. I’ve also tried playing in windowed mode, but it still doesn’t work as it should on my PC. I would greatly appreciate your help in resolving this issue.
