I am using fedora 40 right now, There is a wifi-bluetooth interference for 2.4 Ghz band. Here are my logs for wpa_supplicant and Network Manager.

This was happening when my bluetooth headphones was connected to laptop

wpa_supplicant

I don’t know that your issue is the same, but I had a similar issue with a qualcomm wifi adapter.
Over time the device began intermittently disconnecting then reconnecting and it got to the point that as a result of the network disconnects it began causing cpu core lockups with resulting system freezes and crashes .

Replacing the adapter fixed the issue 100%. This was about 2 years back by now.
