Help with Godot

Hello, I am Brazilian and I apologize in advance for my English. I am working on an MVP, a 2D idle-style game where the player or players are spawned on a map to fight against other NPCs. I am facing a problem: I have noticed that often when more than one player is chasing the same NPC, only one of them initiates the combat animation while the other(s) remain stuck in the chasing animation. I started using Godot recently and I don’t have anyone to help me figure out how and where to fix this. I will leave my repository so you can test it and see it happening. I would greatly appreciate any help you can provide.
