If you want, I can continue investigating. However the error lines are like mixed/fragmented code, and does not exists in the source file. I do not know what happened when...

pop_os 21.04 kernel 5.13 5.15.5 error installing

I just tested both 5.13.0-7620-generic and 5.15.5-76051505-generic on pop os，and did not able to reproduce this issue. Maybe try full system upgrade? `sudo apt update && sudo apt upgrade`

@adityamj it should supported WPA3-SAE, but not GCMP.

It probably a bug somewhere in openwrt or wpa_supplicant or NM. WPA3-SAE should use CCMP-128.
