"CMake: Debug" command freezes on launch

Brief Issue Summary

I am trying to use the debug feature of CMake Tools. When i try to use it it freezes on “Executing command: /usr/bin/lldb --version”

Expected:

1. Run “CMake: Debug” command
2. Normal debug session

Apparent Behavior:

1. Run “CMake: Debug” command
2. The VSCode red line activity indicator moves left to right indefinitely.
