Randomlly Python IDLE doesn't launch (not even the editor)

This is almost surely a problem in your environment, and not a bug in python. This bug tracker is for reporting bugs in python.

I suggest you look for help elsewhere, such as the python-list mailing list (https://mail.python.org/mailman/listinfo/python-list) or the python-tutor mailing list (https://mail.python.org/mailman/listinfo/tutor).

But even if this is a bug in python, you've given us no information to use to help you. Given what you've told us, how would you expect us to respond? You'll need to provide a lot more information before we can even begin to guess what problem you're having.

'Not working' reports lacking information needed to respond, whether to help the reporter of fix a bug, are a common beginner mistake.  The problem is especially acute for IDLE since it is especially targeted at beginners, who may not know the difference between generic python problems and specific IDLE (or tkinter) problems (or even user code bugs).  And beginners may not understand 'try running python (or IDLE) in a command line (or terminal or console)'.  And beginning programmers who have never shared software with other may have no idea what (relatively) large volume of information the authors may to proceed. So I am making this issue about adding information to the IDLE doc about things a user should try and information to include when reporting.
