Glad this is fixed. I reported (probably) the same bug in this thread: Fedora 41 on the Framework Laptop 16
I cannot reply in that thread anymore (as number of replies seem to be limited to 3 for new users), but I can confirm the problem went away with kernel 6.12.11 in Fedora 41 KDE for me too. Previously I also had to use longterm kernel 6.6 to be able to use my Framework 16.
