MediaTek MT7921 WiFi 6 Adapter "Cannot Start" + "Doesn't Exist" + BSOD (DPC Watchdog Violation)

[M2the2ndpower]

System: Windows 11 Home 64-Bit 10.0.22000
Battery or AC: Both
Model: ASUS TUF Gaming F17 (FX706LI.310)
Reset OS: Yes
Frequency of occurrence: Ongoing, Consistant
Screenshot or video: Yes. Your system won't let me post them...
========================
Detailed description：
On one hand, I'm thankful to not be alone here. On the other hand... I know that means some of you are in the same painful situation...
The WiFi option occasionally vanishes from the quick menu at the right, and no, it's not hidden away... It's gone.
As soon as the computer tried to do anything, it would freeze and BSOD with the same error. I didn't need to browse crash logs to guess that the BSOD was from the MediaTek driver. I read online that it could've also been a ssd thing, but that doesn't seem to be the case since both internal and external drives work fine.
So what have I done?
Reset the OS - It booted back up without a wifi option, but it hasn't crashed since.
MyASUS - Completely useless. "Something's being done about the WiFi"? No secret update to install, nothing changes.
Update Driver - Would be nice if it was listed to begin with.
Install/Reinstall Driver - The Driver listed on the ASUS website for my model is the Intel LAN Driver. Didn't work, but it wasn't really going to, was it? Got redirected to the Lenovo website on one occasion. That didn't work either.
Hold Power Button for 60 seconds - I was skeptical, but I recall having done something similar when my Bluetooth adapter had a similar hissy fit. Only worked as a temporarily solution since the WiFi option was gone within a few minutes.
Professionally Serviced / Get a new Laptop - I really don't have the money for that right now and the computer is totally fine besides the missing WiFi error.
[Technically...] I can still use the internet on this laptop because my WiFi extender has an Ethernet option. I don't intend for it to be the permanent solution since a missing WiFi adapter might cause another flurry of BSOD soon. If there is such a legendary driver version or a magical patch that'll fix everything, please get it public ASAP.

After a random windows update, my WiFi adapter has updated to V3.0.1.1336. It also cannot see any nearby networks.

It's a driver issue. That driver won't let me view any networks but the other drivers don't work at all.. There's a driver version that does work, right?

This problem drove me nuts. It's the Bluetooth driver that causes it. The solution required:
Install the my asus app
Open it and click on customer service
Click on live update
Click the "Latest" icon, it has a arrows spinning around it
Unchecl "Show the latest version of updates available"
Download the latest "BIOS For ASUS EZ flash"
Choose a location to save it to
Extract the files it downloads to a usb drive
Shutdown
Flash the bios by entering the bios utility, you gotta hold F2
Go to advanced mode -> select EZ flash Utility -> select the file you just placed on the usb drive and let it update -> ensure your power is in and you don't touch the laptop while it's doing it's thing
Using the method above download the latest mediatek bluetooth and wifi driver installation tools
Uninstall the Wi-Fi adapter and ensure you click remove drivers
Do the same for the Bluetooth adapter
Install both the wifi and bluetooth adapter drivers downloaded in step 12
Reboot
I had to do some last steps
Open Device manager -> Bluetooth -> Right click on MediaTek Bluetooth Adapter -> Update Driver -> Browse for drivers -> Let me pick from a list of compatible -> select the driver at the bottom of the list.
Reboot
Hope this helps, wasted half a day debugging this, really annoying, hate the way windows isn't smart enough to use the latest driver for the Bluetooth or tries one of it's own that doesn't work.

Sorry, the steps I provided are mainly for the disappearance of the wireless network card hardware. After that, the user needs to reboot the laptop and install the driver to use it.
If your problem is that you can't find the wireless network signal around you , I would suggest you bring back your laptop to our service center.
