show when run

When I run my app extension the regular way, everything work just fine for few minutes and I can use the vpn I've configured, but then the extension crashes.When I run the app via xcode instruments, it's not crashing and I can use the vpn as expected.What can cause this weird behavior ? Which error I should look for ?

I'm developing in Objective C with Xcode on a Mac exclusively to run on Mac and all of a sudden when I try to run I get the message: a build only device cannot be used to run this target. If I go to the destination folder, the newly built app is there and runs from Finder, I just can't get it to run from within Xcode, which is inconvenient for testing. What setting am I missing or has changed? Up to now I could build and run with no problem.

Learn to code 1 module is not showing the puzzle on the right viewport. I can write commands and run them, but the puzzle viewport is just blue. Skipping through the lessons I can get maybe 5 of the puzzles to show up. When loading the puzzle viewport, playgrounds will automatically try to run code and fail. On the puzzles that show up, it won't try to run code after the initial loading. And the puzzle works just fine. Playgrounds V14.1 MacBook Pro 13-inch Late 2013 model Big Sur OS

Suddenly starting this evening, Xcode is no longer showing my my build scripts or is it showing me any of the other steps such as 'Copy Frameworks'. The left side where it shows line numbers is showing me a jumbled up count. I saved my project and it even overwrote all my scripts, effectively I've lost what I had!!!! Is anyone else seeing this? This is on the public release versions of Xcode and El Capitan.
