*Edited after super helpful chat with @chili555 that I botched by trying too many things at the same time...

The WiFi adapter works in kernel 5.13.0.20-generic, but in 5.13.0-21 it's inactive and remains inactive after multiple shutdowns/ reboots. I checked that it's active in BIOS and it exists but does not work

$ rfkill list all
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

It is not present in networkmanager or ifconfig, Bluetooth works though which I believe is the same device. Super thankful for any ideas.

The ax500 device works in the 5.13.0-20-generic kernel with

This works again with the now released kernel 5.13.0-22.

sudo apt update
sudo apt upgrade
sudo reboot

and if you never want to see this again:

sudo apt purge linux-headers-5.13.0-21 linux-headers-5.13.0-21-generic linux-image-5.13.0-21-generic linux-modules-5.13.0-21-generic linux-modules-extra-5.13.0-21-generic
