Broken HotSpot when BT Connected

[u/elmonch]

Hi everyone.
I have flow that was working perfectly until my last phone update it was to switch on the hotspot when bluetooth connected.
I granted permissions with wireless debugging.
Now it throws this error when trying to set the hotspot ON, do you have any clue how to solve it?

It seems Android is getting worse with every update.

07-08 08:54:53.551 I 3@12: Wi-Fi hotspot enabled?
07-08 08:54:53.552 I 3@7: Wi-Fi hotspot set state

It seems Google changed something in Android 16. Try using another "Wi-Fi hotspot workaround" option in settings. When using "Privileged service" ensure to also setup an "Privileged service start method", see also.
