Crawl animation stops when colliding with objects. How can I make it not do this?

I've made it to where if you hold c you crawl but if you touch something it stops the animation but it does keep the movement speed change.

local player = game.Players.LocalPlayer
local humanoid = script.Parent:WaitForChild('Humanoid')

local myModule = require(game.ReplicatedStorage.ModuleScript)
local UserInputService = game:GetService("UserInputService")
local ps = game:GetService("PhysicsService")

UserInputService.InputBegan:Connect(function(input, gameProcessedEvent)
	if input.UserInputType == Enum.UserInputType.Keyboard then		
		if input.KeyCode == Enum.KeyCode.C then
			local Animation = Instance.new("Animation", player.Character)
			Animation.AnimationId = "rbxassetid://5512392792"
			Animate = humanoid:LoadAnimation(Animation)
			Animate:Play()
			humanoid.WalkSpeed = 8
			
		end
	end
end)
UserInputService.InputEnded:Connect(function(input, gameProcessedEvent)
	if input.UserInputType == Enum.UserInputType.Keyboard then		
		if input.KeyCode == Enum.KeyCode.C then
			humanoid.WalkSpeed = 16
			Animate:Stop()
		end
	end
end)
