I noticed since August Update I can't turn on 5ghz hotspot anymore.
After some experiment, finally I can turn on the hotspot using some trick.

  1. Turn on Developer mode first (Google it!!)
  2. Navigate to Developer Options > Networking > Tethering hardware acceleration, disable the toggle.
  3. Turn on your mobile data (REQUIRED). Required to trigger the 5GHz hotspot frequency.
  4. Navigate to Connections > Mobile Hotspot and Tethering > Mobile Hotspot > Configure.
  5. Change the band preference to 2.4 GHz first. (REQUIRED !!!). 
  6. After Mobile hotspot established go back to Configure.
  7. Change the preferred band to 5GHz, then Save.
  8. Enjoy.

You can even use it while connect to another WiFi network. It looks like the error is stemmed from OneUI conflict with android 12 Wifi AP/AP concurrency function

For me, when a person needed to connect to the hotspot, I had to change the band preference for 5 Ghz to 2.4 Ghz and then only she could join. So instead of going into all those settings, maybe try switching first?
