I had the same issue after upgrading an apu2 box from Ubuntu 20.04.5 towards 22.04.1. Suddenly my 5 Gb AP did not work anymore.
Some research shows the regulatory issue. APs in the 5GHz MUST work according the ieee80211h standard. The wle600vx or wle200nx HW offered by pcengines does not full fill this requirement.
With the driver upgrade the option of an AP in 5GHz is gone. I did a fallback to 2.4GHz, too. See your Logs I had the same entries. .
I did not find HW supporting ieee80211h for APU2 so far.
