I can't connect to any networks. When I open up Network and Internet in settings, I can't even see a wifi tab. I looked into Device Manager and the MediaTek Wi-Fi 6 MT7921 Manager LAN Card has a warning triangle on it? The one thats yellow with an exclamation markIf I try updating this, it will tell me "This device cannot start. Code 56"I have tried uninstalling and restarting.I'm really confused on how to even handle this. Can I please get assistance?

No WIFI icon in windows 10

So today when playing games, I noticed that the WIFI icon showed me that I am not connected to the internet, but I was still able to browse the internet. I used task manager to restart Explorer, and the WIFI icon disappeared completely. I tried disabling then enabling the driver, but nothing happened. What do I do to fix this problem? If I press the Network Icon in the action centre, it shows the network window, but it doesn't list the wifi networks.
