@VoidableMethod damn, my code is bad because not so long ago I started writing scripts lol. I doubt that anything will help me but I can send you a script so that you can tell me how to solve this problem.

@Rayn 

 it doesn't work, when i run the script with this fix the game just stops working.

I wrote a script to change animations in the game, but after the character dies,
 I try to press the change button and nothing happens, only restarting the script helps
can you suggest quick fix
