Fedora 42/43 KDE, freeze problems

Hey there

I have some problems with freezes on fedora plasma 42, then 43. The device freezes, music stops and mouse pointer is kind of locked. i had 2 external monitor, and once when i disconnected them, it dissapeared. but now i use the notebook without the monitors and the freezes are still there. anyone an idea? is this a common issue?

kind regards

ive tried some stuff with drivers and the hdmi and usb-c→hdmi stuff for the monitors. but did not really help.
