Sonoma 4k monitor keeps going back to 1K 30Hz after restart

[soulblood]

Hello, not sure if anyone run into this issue when the hack restart, screen resolution will go back to 1k 30hz, without the option of 60Hz. I had to turn my monitor off and on to enable the 60hz option.

Everything was fine since macOS10-12.

Hardware-wise, i use 136k+5600, usb is mapped.
