This issue returned after updating Ubuntu and it can't be fixed by the working solution of renaming/removing pnvm file anymore as mentioned in following solutions. How to fix it now?

I notice that there is a later version of the firmware is available. I also suspect that your -63 version may be corrupted. Let's download fresh copies.
With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:
cd /usr/lib/firmware/
sudo wget
sudo wget Reboot and show us:
sudo dmesg | grep iwlWe have to modify your copy of backport-iwlwifi-dkms (8324-0ubuntu3~20.04.4) to work with your newer kernel (5.13.0-39-generic). This newer kernel got installed with a recent Software Update.
Note: Secure Boot must be disabled in your BIOS.
This dkms status output shows us that backport-iwlwifi was never working on your system:
backport-iwlwifi, 8324: added
nvidia, 510.47.03, 5.13.0-37-generic, x86_64: installed
nvidia, 510.47.03, 5.13.0-39-generic, x86_64: installedSo we have to modify it.
sudo -H gedit /usr/src/backport-iwlwifi-8324/dkms.conf
At the top of the file you'll see:
PACKAGE_NAME="backport-iwlwifi"
PACKAGE_VERSION="8324"
AUTOINSTALL="yes"
BUILD_EXCLUSIVE_KERNEL="^((5\.[0-3]($|[.-]))|(4\.))"The BUILD_EXCLUSIVE_KERNEL limits it's use to an earlier kernel from 20.04.
Comment out this line by placing a "#" at the front of that line:
#BUILD_EXCLUSIVE_KERNEL="^((5\.[0-3]($|[.-]))|(4\.))"Save the file. Then do:
sudo dkms build backport-iwlwifi/8324
Note: If the build fails, it'll probably be because you're missing a linux header file. Go ahead and install the missing file, and redo the build command.
sudo dkms install backport-iwlwifi/8324
dkms status should now show:

nvidia, 510.47.03, 5.13.0-39-generic, x86_64: installedReboot and retest your wireless.
Note: If it's still not working, we'll have to get the newer backport-iwlwifi-dkms (9340-0ubuntu4) at .

MSI Z690 Carbon WIFI DDR5: ATX w/USB3.2, 5x M.2
BIOS version 1.21
CPU Intel® Core™ i9-12900KThere's a BIOS update for your i9 at .
Note: confirm that I have the correct web page for your motherboard
Note: do backups before updating the BIOS
Update the BIOS. Retest wifi. Report back.
Update #2:
We tried with a modified backport-iwlwifi-dkms from focal, and a standard impish version with no luck. We tried -67 ucode with no luck.
BIOS has been updated to support i9 processor.
Kernel 5.13.0-37-generic, wifi doesn't work.
Kernel 5.13.0-39-generic, wifi doesn't work.
Kernel 5.11.0-27-generic, wifi works fine.
Run with kernel 5.11.0-27-generic until a kernel > -39 is released, and then retest wifi.
