Not able to use live previews on real device

Hey! I have been getting errors when I try to use lives previews on a SwiftUI project. It even happens when I create a new one from the SwiftUI template.

This is the error message:

RemoteHumanReadableError: Failed to update preview.

Error encountered when sending 'display' message to agent.

Edit: Where should I upload the diagnostics report file?

when I try a live preview on my plugged iPad 6th generation Xcode returns an error.
My iPad is in iPadOS 14.2
A click on the information icon next to the error message in Xcode shows another message telling Xcode is expecting an iPhone 12 device !
