Character cant jump and only move and stucks in fall animation after unragdoll

[1ar4r (Iner1)]

This is super annoying and I have no idea how to solve this problem

function setJoints(player : Player, jointType : string) 
	local character = player.Character
	local humanoid : Humanoid = character:FindFirstChild("Humanoid")
	humanoid.BreakJointsOnDeath = false
	humanoid.RequiresNeck = false
	local descendants = character:GetDescendants()
	for i, object in descendants do
		if object:IsA(jointType == "BallSocketConstraint" and "Motor6D" or "BallSocketConstraint") then
			

			
			if object.Parent.Name ~= "HumanoidRootPart" then
				local ballSocketConstraint = Instance.new(jointType)
				ballSocketConstraint.Parent = object.Parent
				if jointType ~= "Motor6D" then
					local attachment0 = Instance.new("Attachment")
					local attachment1 = Instance.new("Attachment")
					attachment0.Parent = object.Part0
					attachment1.Parent = object.Part1				
					ballSocketConstraint.Attachment0 = attachment0
					ballSocketConstraint.Attachment1 = attachment1
					attachment0.CFrame = object.C0
					attachment1.CFrame = object.C1				
				else
					local attachment0 = object.Attachment0
					if attachment0 ~= nil then
						ballSocketConstraint.C0 = object.Attachment0.CFrame
						ballSocketConstraint.C1 = object.Attachment1.CFrame
						ballSocketConstraint.Part0 = object.Attachment0.Parent
						ballSocketConstraint.Part1 = object.Attachment1.Parent
					end
				end
			end

			object:Destroy()
		end
	end
end

function removeHumanoidRootPartAttachments(player : Player)
	local character = player.Character
	local humanoidRootPart : BasePart = character:FindFirstChild("HumanoidRootPart")
	if humanoidRootPart ~= nil then

	local spring : SpringConstraint = humanoidRootPart:FindFirstChild("Spring")
	local humanoid : Humanoid = player.Character.Humanoid
	if spring ~= nil then
		spring.Attachment0:Destroy()
		spring.Attachment1:Destroy()
		spring:Destroy()
	end
	for i, v in ipairs(player.Character:GetDescendants()) do
		if v:IsA("BasePart") then
			v.CFrame = CFrame.new(v.CFrame.Position)
			v.Anchored = true

	end

function Ragdoll.unragdollPlayer(player : Player)
	setJoints(player, "Motor6D")

end
	

return Ragdoll

Its always falling and getting dragged, why do Roblox do this.

If I Can’t find a solution to this directly, can writing my own character system work? (custom movement, force disablement of fall animation and implement fall checks using constant raycasts per 0.5 seconds)

also cant swim
