I am getting a message in my debugger:

The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix

Answer 1

I ran across this same error with zero idea of what to do next. I tried the accepted answer and my project didn't have any breakpoints at all.

Turns out I had an observer that I didn't remove and every few times I would push off/on the vc that contained it it would eventually crash with the op's error. I had to enable zombies to figure out which vc was causing the error. I had to manually go through the code line by line to realize I didn't remove the observer. Once I removed it everything worked fine.

// not removing this caused the error
playerItem?.addObserver(self, forKeyPath: #keyPath(AVPlayerItem.status),
                                options: [.old, .new],
                                context: &playerItemContext)
