I also cannot boot with the latest installed kernel linux6.1 anymore. It hangs with this error message:

I tried to downgrade mesa as suggested by philm, but to no avail. Firmware was already up-to-date. Unfortunately, I cannot install a newer kernel as suggested. I posted about it here
Luckily I still had linux515 installed, which boots fine. I’m trying to find a way to post journalctl and dmesg. I just failed doing so - too many characters.
