Hi there, I still encounter that problem and nothing at SO neither here helped me to solve the problem. But I found a workaround at least. In Xcode click on your project name (next to the device) where you can change the scheme. Click edit scheme -> select run from the left control pane and uncheck "Debug executable". Like this it starts at least. Hope this helps someone else out there I have no clue where this bug came from. Everything worked great, I had no break points etc. The only thing that happened before the error I can remember was I connected a "managed company device" and Xcode rejected it. After that I didnt work anymore. Xcode Version 13.1 (13A1030d) OS Monterey
