My Intel WiFi AX200 - MSI X570 wireless network adapter recently stopped working. I'm running Ubuntu 20.04.

I tried adding the Intel® Wi-Fi 6 AX200 160MHz .ucode firmware file to /lib/firmware from Intel's website with no luck.
I also tried a fresh 20.04 installation. One common item between others that I see having this issue is that they also dual boot Windows. The weird thing is I used Ubuntu 20.04 for 3+ months, and then swapped back to Windows for a few days, and upon booting back up in Ubuntu it no longer works. Switched back to Windows again to verify that the device actually works, which it still does.
