Xcode "Failed to get the task for process -1" iOS15

am new to working with iOS, so apologies for what may be a simple question. I have an iOS app that recently stopped working with upgrade to iOS 15. I loaded my previous xcode project into the latest version of Xcode and tried loading again on my iPhone. I'm getting an error stating: "Could not launch "my app name"" "failed to get the process for task -1". In details it provides this additional information.

Appreciate any thoughts or input!

A note : when you paste the log, use Paste and Match Style to avoid the king size characters that make it harder to read. So that will be as easy as in your S.O post.
