wifi and bluetooth not working ios 17.4.1 on iPhone 15 Pro

Wi-Fi and Bluetooth connections will not enable through control centre, or through the settings app.

In control centre, the icons are greyed out and struck-through, when pressed they turn blue for a few moments and a prompt displays at the top of the screen "Wi-Fi/ Bluetooth connections enabled" However after a few seconds they return to the greyed out, struck-through state.

In settings app, the on/off buttons can not be switched and the 'loading' wheel spins indefinitely.

Things I have tried so far to resolve the issue:

• Forced Restarts
• Resetting Network settings
• Checked for updates, only available is the 17.5 Beta 3 which I'm hesitant to install beta software if the 'tried and tested' software is having these issues.
• Tried multiple wi-fi access points and bluetooth devices.

Any help would be appreciated
