Just leaving this here in case it helps anyone.

I did try all or most of the answers and none worked.

I kept thinking what has changed since the last time I ran the app successfully.

Then it hit me! I updated my Mac. (but my iPhone wasn't, and had an update).

Once i updated my iPhone it worked fine. (Also, this might be specific to Xcode 16 or OS 15.4, which had some permissions update that wasn't there before.)

PS: I do not update my iPhone because I keep having connectivity issues with regards to Android Studio and wireless debugging. It's a blessing and a curse.
