MSI GS65's screen remains black on boot since Linux 6.4.1

This problem occurred since Linux 6.4.1, the last working kernel version is 6.3.9. I was busy back that time, and didn't capture the dmesg log until today (it's 6.4.9 now).

The laptop has a RTX2060 mobile graphic card, with i2c_nvidia_gpu and wmi blacklisted. So the previous solution does not work, and I couldn't find new posts on this issue since the 6.4.1 update. The full log is attached, and the highlighted part:

Screen has been black without any loggings since grub loaded linux and initramfs. I dumped these log after rollback of 6.3.9. However from the log many services still ran correctly, I guess it may be related to backlight or nvidia card problem. But I don't know how to fix

dmesg of failed boot on Linux 6.4.9
dmesg of successful boot on Linux 6.3.9
lspci -k
