Error when attempting to connect to a Mac

Question

I am getting and error when attempting to connect to my Mac to build my Maui App. The UI says Error: 'I' is an invalid start of a value. LineNumber: 0 | BytePositionInLine: 0.

The log files show the error details below. I have cleared all the caches, removed and re-added the Mac, restarted both devices and updated to the latest VS. I have also installed Xcode 16 and verified that the Simulator runs from there.

Does anyone have any ideas what might be causing this issue?
