Cannot load the AnimationClipProvider Service

I want to fix a major bug that causes my character to glitch crazy (Every 1 or 2 frames to precise) and I know it is not my character because it just resets to the starter-character.

Whats happening:

I have searched the Developer Forums but found no solution

And my gam… oh wait experience uses @EgoMoose 's wall walking system.

I got the animation working by replace Humanoid:LoadAnimation() in the Animate script inside a character with

local animator = Humanoid:FindFirstChildOfClass("Animator") or Instance.new("Animator", Humanoid)
if animator then
	local track = animator:LoadAnimation(animType[idx].anim) -- bug here
	track:Play()
end

But the glitches still happen (Flickering)

I fixed it! It turns out I had a broken system that changed my character in a loop.
