Player gets stuck in a certain position while trying to use the tool?

Everytime a player selects my gamepass given tool they get sent to a certain position with the gun in their hand and they are unable to move?! help please. Here is my gamepass script if anything is wrong?

local player = game.Players.LocalPlayer
local ownsGamepass = game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId,9027783)

if ownsGamepass then
 local sword = game:GetService("ReplicatedStorage"):WaitForChild("Flintlock"):Clone()
 sword.Parent = player.Backpack
end

local player = game.Players.LocalPlayer
local ownsGamepass = game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId,8981498)

if ownsGamepass then
 local sword = game:GetService("ReplicatedStorage"):WaitForChild("Rifle"):Clone()
 sword.Parent = player.Backpack
end
