Is that regulatory domain set before rtw_8852be is loaded?
I have a file /usr/lib/modprobe.d/70-cfg80211.conf that contains the line "options cfg80211 ieee80211_regdom=US". That sets my regulatory domain before any wireless drivers are loaded. If you already have such a configuration file, then the utility may not know how to interrogate it correctly. The place where regulatory domain errors shows up in the 5G band. The default configuration will have all channels flagged with "(no IR)", which will prevent the AP from broadcasting beacons. If your setup is working, then the utility is wrong.
