Sword doesnt detect the first hit on another player, how can I fix this?

I ran into an extremely annoying error, For some reason the knife tool I made cannot detect hitting a player on the first swing. There are no error's aside from:

17:33:35.149 - Replication: Can't create default object of type Players

I even put a print function after each "if" statement to see if the script made it that far, It doesn't detect the humanoid on the first swing, what's even weirder is if I stand still and continue to swing in the same spot after the first one didn't register none of them will, unless I move my character and try hitting the humanoid again. I did multiple server tests hitting the humanoid and ensuring the handle, which is the whole tool is touching the humanoid.

This is very annoying and I can't seem to find out what's wrong.

-- End Of Script

You can see my prints near where the error is, it never passed any of them on the first swing or any of the swings after that if I stood in the same spot from my first swing.

Knife local script.

I don't know if this is relevant but I included it anyways, this is all of the knife's scripts. It uses a remote event in preparation for filtering.

I hope I get answers, the last questions I had seemed to be ignored.

Thanks in advanced.

How can I get the first hit of my knife tool to be detected when hitting a humanoid.

It is only the first hit in the instance, I can hit the humanoid, it not do any damage, move hit the humanoid then it does damage and I can kill it. When it respawns I can do it again with out issue.
