MacOS CLI prof-startup results in hanging program

[rzhao271]

On macOS:

1. Run code-insiders --prof-startup <some-project-directory>
2. After the profile is taken, a dialog should appear. One of the options is "Restart". Press that option
3. 🐛 VS Code doesn't restart, and the user must go to the dock and force quit the application.

Thanks for reporting, I actually found this too yesterday and also figured out it was not a regression from your changes.

I am also seeing this issue but wanted to add that errors similar to the ones below are also seen in the terminal that appear just before one is prompted to restart.

code-insiders --prof-startup .
