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

You used anchor the tool and makes tool grip to force the people hold it. So remove the anchor on the tools.

Unanchor the tool.

Unanchor the tool's parts
