I also have AX200 card with errors as mentioned above, and no wifi interface at startup.
I tried solution from @invalidhandle and it worked:
I left alone iwlwifi-cc-a0-50.ucode.zst (I don't have version 48) in /lib/firmware and rebooted. Then wifi was ok and I could connect to internet.
I tried also with iwlwifi-cc-a0-77.ucode.zst without success (no interface showing up).
I'm using kernel 6.6.2-arch1-1.
