Motor6D doesn't work when playing animation

[MalAllie]

1. What do you want to achieve?
   I’m trying to create an equip animation for my pistol.

2. What is the issue?
   When I try to make animations on the humanoid, the motor6D for the gun doesn’t work. In my animation, I used the motor6D to rotate the gun.

3. What solutions have you tried so far?
   I am looking for solutions in the developer hub, but I don’t see anyone having the same problem. My theory is one of the inverse kinematics scripts I have is interfering with the animation (The inverse kinematics is for making the player’s character look up and down).

--Snippet of my code (this is on the server)

Tool.Equipped:Connect(function()
	local character = Tool.Parent
	local humanoid = character:FindFirstChildOfClass("Humanoid")
	params.FilterDescendantsInstances = {character}
	
	local RightHand: Part = character:WaitForChild("RightHand")
	local ToolAttach: Motor6D = RightHand:WaitForChild("ToolAttach")
	ToolAttach.Part1 = Handle
	
	idleTrack = humanoid:LoadAnimation(Animations.idle)
	idleTrack:AdjustSpeed(0)
	idleTrack:Play()
	
	attackDebounce = true

	task.wait(equipCd)	
	attackDebounce = false
end)

This is what the animation is supposed to look like:

This is what the animation looks like in game:

Can someone help me find a solution for this? Thank you!!!
