Doesn't quite work for me (Index was outside the bounds of the array)

hi! I imported the engine into godot 4, and it is sorta working. I run the test scene, and it runs fine, but when I try to click any buttons, it gives me an error, and nothing happens in the game window. I have linked a screenshot of the whole error code and stack trace, I have no clue how to fix this :/

I'm sorry for that, I'm developing a character I can't push to the main branch and forgot to clear all the references for them
It should be working now
