The usual way to debug freezes is to attach the debugger to the frozen
process, and produce a backtrace. Also, etc/DEBUG describes how to
debug infinite loops (if that is what's happening); search for "If the
symptom of the bug is that Emacs fails to respond".

That is always the preferred way, when you are running the development
code.

Is the above the starting point you were looking for? If not, please
elaborate about what would you like to find as a starting point.
