After a certain amount of uptime, the OS is irreversably unable to detect the wireless adapter (MT7921K in this case). I previously "fixed" this by restoring the original Windows 11 install and then installing Debian 12 -- this worked, but I didn't realize long uptimes were the cause and now it has once again stopped working.

I found this askubuntu post but unlike that user, it seems like I have multiple aliases assigned to the mt7921e module. I'm not sure how to solve this problem, and would appreciate any help. Thank you.

OS: Debian GNU/Linux 12 (bookworm) x86
Host: Modern 14 C7M REV:1.0
Kernel: 6.1.0-10-amd64

Network controller [0280]: MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz [14c3:0608]
    Subsystem: MEDIATEK Corp. MT7921K (RZ608) Wi-Fi 6E 80MHz [14c3:0608]

user@localhost ~> sudo modinfo mt7921e | grep alias
alias:          pci:v000014C3d00000616sv*sd*bc*sc*i*
alias:          pci:v000014C3d00000608sv*sd*bc*sc*i*
alias:          pci:v000014C3d00007922sv*sd*bc*sc*i*
alias:          pci:v000014C3d00007961sv*sd*bc*sc*i*

Update: I followed the advice in this post and did a 60-second hold on the power button. Upon rebooting there was a "secure boot violation". I disabled secure boot and booted successfully into the desktop to find that my wifi was indeed working. However, my touchpad has stopped working.

Update 2: On the previous boot I had my mouse plugged in during boot. I removed the mouse and rebooted, and after booting the touchpad was recognized and the mouse worked as well.
