Thanks Jan, for pointing me in the right direction. After installing firmware-mediatek, my issue is solved now.
I have missed the earlier log entry, where the firmware file could not be loaded. I just didn't notice that there is a separate package for mediatek firmware files now. Because they used to be part of firmware-misc-nonfree until version 20230625-2. But they're no longer present in firmware-misc-nonfree 20240709-2~bpo12+1. Maybe I just got hit by this, because I've disabled recommends in my apt config. And firmware-mediatek is in the recommends of firmware-misc-nonfree :-) Thanks again everyone for your replies. Have a nice Sunday.
