Help with Animation Issue

Hi guys, I’ve made an animation for a cutscene, but idk why when I play it in the character it’ll be buggy. I tried to check in the rig where I made it, and if I unanchor the HumRP the animation will get as buggy as if I play it in the char, and if I anchor the HumRP it won’t. Ofc I tried to anchor the player HumRP but this won’t work too.
