Ubuntu 20.04 - No WiFi adapter found

I built my first PC today, and installed Ubuntu 20.04.03 LTS on it. Ubuntu is the only OS on the machine. The build is as follows

MSI Z590 Pro Wifi Motherboard
Intel i7-11700K CPU
G.SKILL Ripjaws V Series 32GB (2x16GB) DDR4 3200 RAM
Corsair CX-F CX550F 550W PSU
Samsung 970 EVO PLUS M.2 2280 1TB PCIE 3.0 x4 NVMe SSD
be Quiet dark rock slim CPU Cooler

The motherboard has wifi & bluetooth built in. (WiFi card is Intel AX210 160MHz) The bluetooth is working fine but the WiFi is not: I get the error "No WiFi Adapter Found".

Kernel version is: 5.11.0-37-generic

The output from lspci -knn | grep Net -A3; rfkill list:

That spits out Failed to run INIT ucode: -110, but when I look up that error, none of the fixes work for me. I'm currently connected through USB Tether to my iPhone, and have tried running sudo apt-get update && sudo apt-get upgrade but it doesn't fix it. I also tried re-installing Ubuntu, but to no avail.

I have no idea what else to try. Any ideas?

It looks like the solution is to delete /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm file.

Beware that the file will appear in case linux-firmware package gets an update. If the issue won't be fixed at that time, Wi-Fi will stop working again.
