dmesg filtered on iwlwifi

I am using an AX210 wifi chip and the only kernel that works with this wifi card is version linux 5.11.10, because it comes with iwlwifi 59.601f3a66.0. The newer kernel versions like 5.12.9, come with iwlwifi 62.49eeb572.0 and the wifi interface never comes up. I am not sure what changed in the newer versions...

Attached as wifi_not_working.txt is the dmesg log for kernel 5.12.9 with iwlwifi 62.49eeb572.0. When I use kernel 5.11.10 and iwlwifi 59.601f3a66.0, there are no error messages and everything works.
