WiFi and Bluetooth are greyed out

I recently update software to IOS 15.4 on my iPhone 12 Pro. I now have greyed out toggles for WiFi and Bluetooth. I can't google then on.

Do a forced restart:

Press and quickly release VOLUME UP
Press and quickly release VOLUME DOWN
Hold the SIDE button until an Apple logo appears (15-30 seconds), ignoring "slide to power off" if it appears

The operative word here is QUICKLY; and try it a couple of times, the timing is a little tricky.

If that doesn’t fix it, restore the phone to factory settings, then to a backup:

And if that doesn’t fix it use the Get Support link at the top of this page to discuss hardware repair options with Apple.

Thanks Lawrence. I tried your suggestion that a few times and haven't had luck yet. I had already done a restore and then restored from my back up. The backup completed recently and the apps are still updating over cellular connection. So, I'll wait until all apps are updated though I can't see why that would interfere with your process). Then I'll try a few more times as you suggest.

Earlier today and yesterday, before I restored the iPhone, if I shut down and and restarted I would get connection to both wifi and bluetooth. But invariably, after some time ranging from 10 minutes to an hour, they would both drop with the toggle buttons locked.

That sounds like a hardware failure of the chip that manages both Wi-Fi and Bluetooth.
