I have the same problem with a M.2 AX200 card installed in a laptop running Ubuntu 20.04, with kernel 5.11.0-40-generic.
I noticed that the WiFi works fine when I force the driver to load the firmware "iwlwifi-cc-a0-48.ucode" by renaming newer versions of this file, and this also worked with previous kernel releases.
After every update of linux-firmware, however, the renamed files are replaced and the WiFi starts crash-looping again.
Thus, I am confident that the issue is specific to the newer firmware releases for the AX200:
- iwlwifi-cc-a0-55.ucode
- iwlwifi-cc-a0-59.ucode
- iwlwifi-cc-a0-63.ucode
Does anyone know what was changed in these firmware revisions?

For reference, here is the error message printed when iwlwifi-cc-a0-55.ucode is loaded. It repeats over and over until I delete the aforementioned firmware file:
