Issues are for problems with the kata, not problems with your code. It sounds like your code is too slow, or perhaps gets caught in some kind of loop. You can post your code here (make sure to mark it as a Spoiler) if you want help debugging it.

You're probably not returning anything, and without seeing your code it's impossible to tell what's wrong for sure. In any case, not a kata issue.

I checked the Python version of the kata and it seems to work well. Most probably your solution is not correct. Please see this bullet point for a potential cause: https://docs.codewars.com/training/troubleshooting#.print-vs-return or see if the linked article has anything helpful.
