AW3423DWF, black screen issues

1 day ago I update the firmware from 104 to 107. It was working fine. Next day I installed POE 2 and played for about 6 hours and then game crashed. After the crash the Monitor started to have Black screens, every 1 min or so it goes black and switches back on. LED on the power button of the monitor stays on during the black screen. Tried disabling HDR, Different Resolutions, Different Frequencies (60Hz,100Hz,165Hz), Switched DP on GPU. Problem still persisted. After swapping DP on the monitor from DP1 to DP2 didn't have black screens for last 40 mins. Now I'm just trying to figure out If it's the firmware update that might cause this? Is it possible that something malfunctioned on the DP1 during the game crash now and it will be unusable. Is it possible to roll back the firmware?
