VoWifi missing

Hi, I somehow played / messed around with my OP8T and am now no longer able to enable VoWifi and VoLTE, also 5G is not working. Both options are checked in the SIM settings and the icons are enabled in the system settings but the phone doesn't connect and the icons don't show up.
It used to work till I played around ...

I just re-flashed OOS which didn't change anything :-(

Any suggestions?
