AX200 160mhz on MSI mainboard doesn't work

[VincentH]

I have a MSI X570 Unify board which has AX200 160MHz embedded. Wifi stopped working after I did a power off when my OS was stuck. Something I noticed in the dmesg log saying OTP is empty and no valid mac address is found. I did a search in the community, but hasn't found any similar posts. Bluetooth seems working fine though.

What can I do to recover from this?

After a kernel update (5.12.13), issue is recovered. Thanks for the response.
