I fixed this by just using a different computer with XCode 16 beta 1. I did the USB connection, accepted prompts to trust the phone and device, and did a sync of any debugging symbols. I created a new app just to test, and it worked ok. Was then able to connect with my old computer and all went well.

Oh yes, I used that Car Play Music Sample to add CarPlay to my app and it seems to work good but now I need to make sure Siri works with CarPlay and the main app, the watch, HomePod and everything else. I'm just running into conflicts with INPlayMediaIntent plus I'm working on a Radio app so when a user says "Hey Siri, play Beatles Radio" the phone tries to play Beatles in my music library instead of my app. I have 40 other radio stations with the word "radio" in the name, so I'm dealing with that. I'm getting lots of other errors when I try to upload to appstoreconnect, but will deal with them later: ITMS-90626: Invalid Siri Support - '' is not a supported intent type Though you are not required to fix the following issues, we wanted to make you aware of them: ITMS-90626: Invalid Siri Support - No example phrase was provided for INSendMessageIntent in the 'pt-br' language.
