ZorinOS 17 WiFi Adapter keeps disappearing after random time, even when actively used

Hi Forums,
I have a WiFi issue like some people reported, but so far, none of the fixes worked.

I run a Lenovo E15 G4 with Zorin17 only on it, all updated.

The symptom:
After some time the WiFi-Adapter disappears and only a reboot will bring it back. It is independent on which WiFi I am connected to and the timeframe does not seem to follow anything regular. I have set wifi power saving to =2, but it also happens while I'm using the computer actively.

Kernel version is 6.5.0-28-generic

lshw gives me
