Whole system is grey in HDR, didnt happen before. Tried everything I could find online. Why?

Hey, so I just migrated from LG C2 to MSI MPG 321URX.

I was used to running HDR on all the time. Never had any issues system looked fine and the games too.

Sadly now when I have HDR on the system is completely washed out and grey. I tried autoHDR on/off and the HDR calibration app but nothing changes that. When I plug the C2 back in it doesnt happen. Is there some magic settings I am missing? I tried the True Black and Peak Brigness monitor settings but doesnt change anything.

I am losing my mind and thing about returning it. I do not want to switch it on/off every few hours. Did anybody had this issue and solved it?

Thank you.
