    I found a temporary solution! Just turn on the HDR then set the "SDR content brightness" slider to minimum, turn off HDR and voila, no more need sleep to have normal brightness. I'm now on 23H2 with RX560.

Not sure if this applies to any of you but my monitor is an LG UltraGear and I was able to fix the issue by going to C:\Windows\System32\spool\drivers\color and deleting ULTRAGEAR.ICM. A driver I installed yesterday had created that file and my issue started after that.

Rile_Zugo Deleting the icm file worked for me. Thanks a lot.
