MT7922: Activation of network connection failed

Using the MEDIATEK MT7922 adapter on Fedora 40 (Gnome), up to date, with the mt7921e driver as shown with inxi. Laptop model is Lenovo Thinkbook 13s G4 ARB

To explain the issue: after powering on the computer to the login screen, you can notice in the top right that it takes a noticeable extra delay in connecting to the network (10-11 extra seconds) than it used to, (which used to be basically instantly). Beginning several minutes after connecting, the network will constantly disconnect during use, saying “Activation of network connection failed” in a popup in Gnome. In the majority of cases, it is unable to reconnect, requiring a reboot. In some cases it manages to reconnect, but it may or may not disconnect again after some time. This has left the laptop unusable for anything requiring an internet connection. This issue began on my home network over a month ago; I was going to wait it out initially. For the past year or so, I only had this issue with my school's network; every other network worked perfectly fine. Now my home network is affected.

An interesting note is that this does not occur on all wifi networks. For example this DOES occur on my Rogers Canada (cable) home network, as well as on my school‘s network. But it DOES NOT occur on my friend’s Bell Canada (DSL) home network, nor on my own iPhone data hotspot. Very weird behaviour.

This does not seem to be a hardware issue; the issue doesn't occur on windows whatsoever.

No source file, test, or entry point is identified in the report. Start by reproducing the MT7922 connection failures on Fedora 40 across the affected and unaffected networks, then trace the reported activation failure to determine what evidence is needed for a driver fix; done means the repeated disconnects no longer occur.
