Repost of my question deleted from askubuntu for being off-topic because my distro is Ubuntu Cinnamon Remix.
Description of the problem
I forgot to plug in my laptop as it was syncing files from a distant machine overnight. It inevitably ran out of battery and went into hibernation mode. Once on, I could no longer connect to Wi-Fi. I can connect to the internet through ethernet, but this is not ideal as it uses a dongle that takes up my charging port, and also limits mobility. I've followed many troubleshooting guides, including (but not limited to):
What I've tried so far
I've tried reinstalling network-manager through APT and backport-iwlwifi from source.
Following link 10, I have tried re-downloading all of the iwlwifi*.ucode files from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/ and replacing the existing ones in /lib/firmware, to no avail.
Following link 1, I have tried loading the Ubuntu Cinnamon ISO (the ISO of my distribution) onto a USB thumbdrive and installing drivers from there. The iso is recognized by my system as a virtual CD-ROM drive, but the Installable from CD-ROM/DVD option in the Software & Updates dialog remains grey and unresponsive, and says "insert the medium into the drive". I've also tried mounting the ISO with AcetoneISO, for the same result.

Closing statements
My best guess is that I need to reinstall a corrupted driver, but I just can't figure out what exactly to reinstall. Any help sorting this situation out would be greatly appreciated.
Update
Thanks to Freddy for the suggestions. I've tried deleting iwlwifi-ty-a0-gf-a0.pnvm, deleting the .ucode files for the versions more recent than 59, deleting everything and re-importing the latest driver binary provided by intel, and every combination of the above, to no avail.
Here is some of the new output of dmesg:

[ 2.994764] iwlwifi 0000:aa:00.0: Detected Intel(R) Wi-Fi 6 AX210 160MHz, REV=0x420
I posted the rest on pastebin. So we see that the new firmware versions are being skipped and it's loading version 59, but something goes wrong after that.
I also found some old USB Wi-Fi antennae:
- TRENDNET AC600 which I've gotten working out of the box with several other Linux machines
- TP-Link Archer T2U Plus which isn't supported out of the box but I got a custom driver working for it on other Linux machines
Neither of these work. They do show up in lsusb but nothing in rfkill, and the LEDs on the antennae don't turn on. So it seems that the problem isn't limited to the built-in Wi-Fi card. What could be causing system-wide failure to handle Wi-Fi devices?
Update 2
The problem is fixed, I'm not sure why. I performed a pretty big upgrade, most notably including the following packages: linux-generic, linux-image-generic, linux-headers-generic, linux-generic-hwe-22.04, linux-image-generic-hwe-22.04, linux-headers-generic-hwe-22.04, linux-generic-hwe-20.04, linux-libc-dev. I restarted my computer after the update which booted me into GRUB (it usually just boots into Ubuntu). I remembered someone mentioning that a similar problem needed fast boot disabled to be fixed, so I took the opportunity to boot into my BIOS and disable fast boot. I rebooted, and now Wi-Fi works.
Here is some updated info in case this helps anyone:

I did a diff on the iwlwifi-* files in /lib/firmware and a backup I had made, and they're apparently identical.
