So, I’ve at least managed to fix the issues around initramfs and the Nvidia driver, so my computer is running on the newest kernel again. Nevertheless, the mt7921e driver keeps failing and causing Firefox to freeze, and my computer to crash or fail to shut down.

The last time this happened, a moment ago, my computer, instead of shutting down, went into the black screen slowly getting filled with text. The text read stuff like,

• mt7921e driver own failed
• mt7921e timeout for driver own
• mt7921e chip reset failed
• mt7921e Message 00020001 (seq 7) timeout
• mt7921e Message 00020002 (seq 8) timeout
• mt7921e Message 00020002 (seq 12) timeout
• mt7921e not ready 65535ms after DPC; giving up
• pcieport AER: subordinate device reset failed
• pcieport DPC: containment event, status:0xf01: unmasked uncorrectable error detected
• pcieport PCIe Bus Error: severity=uncorrectable (Non-Fatal), type=Transaction Layer, (Receiver ID)
• pcieport device error status/mask=00200000/00010000
• pcieport [21] ACSViol (First)
• mt7921e Message 000046ed (seq 14) timeout

I have tried the following since last time:

• Went into UEFI, but couldn’t find any wi-fi settings there.
• Disabled wi-fi by right clicking on the icon in the taskbar, turning the computer off and on again, and re-enabling wi-fi.
• Updating network-manager.

It would appear that it is possible to physically remove or re-seat the wi-fi card by opening my computer up, but I’ll leave that as a last resort for now. Trompete also suggested that I could “blacklist/disable the internal Wifi in Linux”, but this seemed to be specifically for when I get a wi-fi dongle. Several people have now suggested that I get such a dongle.

Looking up similar issues (albeit on a different distro, Arch, whereas I use Mint) I see mentions of “disabling network-manager’s MAC address randomization” and “disabling ASPM” as potential remedies. I have not tried these yet.
