For many different situations a python add-on can crash/stuck/freeze
this for various different cases where add-ons not intercepting data or generating unexpected exceptions,
can cause infinite loops due to the former or derived from other problems

whatever the case Kodi is currently unable to handle python add-ons that become unstable or unresponsive
and offers no way (that i am aware of) to force close an add-on and related service

this often happens while kodi is showing the wait screen (animated loading circle)
when you try to press "back" to cancel the operation, you can see a first blinking of wait screen, but do nothing
is still stuck in the wait screen, and the only way to "unlock" the situation is to terminate the execution of kodi executable and rerun kodi app

this is particularly inconvenient with systems such as CoreElec/LibreElec where Kodi is embedded with the OS

I think when you try to cancel an add-on operation by press "back" at least on wait screen
kodi should allow after some seconds of time or more pressed "back" to allow ask the user if you want force close the unresponsive addon
and return to main menu
