Research direction
Start with the attached openwrtlog.txt and the /etc/config/wireless configuration on OpenWrt 23.05.3, then compare the radio0 behavior with hwmode set to '11a' and '11g'. Trace the MT76x2e radio initialization and configuration path; done means the 2.4GHz radio starts correctly without the manual hwmode change.
