I made additional changes to the EDID:

Added extension override data block.
HDMI data block: Max TMDS clock should be 340 MHz.
HDMI 2.1 data block: Max TMDS character rate should be 600 Mcsc.
Deleted 4:2:0 capability map data block since that ties with the TV resolutions data block.
Set the preferred flag in the detailed resolution.

Try importing this:

If that doesn't help, what if you keep 640x480 @ 60 Hz enabled under established resolutions?

Your file worked I have 144hz only now and the Nvidia Control Panel is fully functional. It seems whatever was breaking the Nvidia driver must have been in those changes you did because those are the only things different.

Also I added 2880x2160 under the DisplayID 1.3 detailed resolution block, and that triggers a signal change only one time per boot then for subsequent resolution changes GPU integer scaling works to keep sending 3840x2160 144hz to the monitor at all times so no more signal swap black screens and broken monitor settings. Super happy now, thanks so much for your help. That's a game changer for this monitor!
