Gray tones are off in canvas

Thank you, I´ll try that. Switching between the Display and sRGB profiles doesn´t seem to do anything at all, and i´d imagine that doing so would affect every program, what irritated me was the fact that the whole Interface was displayed correctly, as well as the previews of my last used files on the home screen, it was only inside the canvas and the color picker, but because I changed everything to sRGB I thought that could not be the issue. Need to set the Colorprofile to my Display profile in Photoshop, idk. At least I know now how to work around it and maybe I can solve it around that.
Have a nice day 🙂

So if you load (temporarily) sRGB as your display profile, do you still see the color cast? I suspect this is a display, preview issue with the display profile. It could be corrupted. 

The only way to 'correctly' preview using a good display profile is using hardware to measure a calibrated state then build an ICC dispaly profile of that condtion. 

And yes, it could be Windows 11 which I've been hearing about such issues in terms of color management. I'm on a Mac so I can't give you further info about that OS. 

Do go back and reset ACR (ideally to ProPhoto RGB but Adobe RGB (1998) if you wish), that's not the issue. 

Thank you for the fast reply.
Unfortunately nothing of the above solved the issue. I updated the GPU drivers, my CPU has no graphics support. I uninstalled Photoshop, updated it to the newest Version (V 23). I also went as far as changing the Color Profile in Camera Raw which was set to Adobe RGB 1998, changed it so sRGB. I dont have the option of calibrating my display via hardware, it´s a relatively old BenQ and I use Photoshop exclusively on a semi-professional hobby basis, but the Issue I ran into is not neglectable. I actually solved the problem by changing the color profile to my Displays colorprofie when creating a new project. This has to do for now as a temporary workaround, I need to do some mor investigation and troubleshooting when I have more time, but I´m absolutely certain that it is a problem due to the new windows 11 upgrade.

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, go to Preferences > Technology Previews... and check "Disable Native Canvas" - then restart Photoshop. Better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.

Misspelled grey...
I just checked, everything is fine on my laptop. I restartet the Computer, checked for Nightmode, but it appears to be a photoshop problem. Colors are perfectly displayed on websites and everything outside of photoshop. Even the Interface is a normal grey.
