Cant use phone after 6.1 update

[DanWalk]

Hi

Phone has been updated to One UI  6.1.

Upon starting Phone goes to the welcome screen. 

Next screen shows the advanced intelligence improvements welcome screen from the update.

Next screen goes blank then shows a Samsung policy could not load because the web page is not available. 

Has the update killed my WiFi and SIM connectivity?

To get it working i started the phone in safe mode.

Previously i had performed soft resets and wiped the cache partition several times which didn't work.
