I've updated my iPhone to iOS 14.3 and it required me to update Xcode to 12.3 too. But Xcode now gives me the following error whenever trying to run/debug the app through the device.

Errors were encountered while preparing your device for development. Please check the Devices and Simulators Window.

I tried restarting Xcode, reconnecting the device, changing deployment target etc. with no luck.

if you updated you iOS to latest beta version, you should also use latest Xcode beta version.

Or else restart your device.
