Script yields after requiring module?

Hey, so I made a FPS framework. In the main client script where input is controlled etc, the script doesn't run. I placed a bunch of prints in it to see where it is yielding, and apparently it's a line that requires my fps module. Here is the script:

print("printerino 0") -- prints
local uis = game:GetService("UserInputService")
local rs = game.ReplicatedStorage
local runService = game:GetService("RunService")
print("obama") -- prints
local modules = rs:WaitForChild("modules")
local guns = rs:WaitForChild("guns")
local gunRemotes = rs:WaitForChild("gunRemotes")
print("yeet") -- prints
print(modules:WaitForChild("fpsModule").Name) -- prints, used to check if the module exists
local fpsModule = require(modules:WaitForChild("fpsModule")) -- this line right here apparently stops it, no errors in the output
print("modulerino") -- this does not print
local cam = workspace.CurrentCamera
print("camerino")
local player = game.Players.LocalPlayer
print("ye")
local newGuns = {}

local ownedGuns = {
	
	nil,
	"pistol",
	nil,
	
}
print("yeeterino")
local newGun,ammoData = gunRemotes.new:InvokeServer()
print("gunnerino")
for i,v in pairs(guns:GetChildren()) do
	
	local gun = fpsModule.new(v.Name)
	gun.ammoData = ammoData
	
	table.insert(newGuns,#newGuns+1,gun)
	
end
print("viewmodelino")
for i,v in pairs(cam:GetChildren()) do
	
	if v.Name == "viewModel" then
		
		v:Destroy()
		
	end
	
end
print("after viewmodelino")
local working
print("printerino 1")
local function equip(gun)
	
	if working then return end
	
	working = true
	
	if gun.currentGun ~= gun then
		
		if gun.equipped then
			
			gun:Remove()
			
		end
		
		gun:Equip(gun)
		
	end
	
	working = false
	
end
print("printerino 2")
uis.InputBegan:Connect(function(key,gpe)
	
	if player.Character then
	
		if key.UserInputType == Enum.UserInputType.MouseButton1 then
			
			fpsModule:Fire(true)
			
		end
	
	end
	print(ownedGuns[2])
	if key.KeyCode == Enum.KeyCode.One and ownedGuns[1] then
		
		equip(ownedGuns[1])
		
	elseif key.KeyCode == Enum.KeyCode.Two then
		print("equipped")
		equip(ownedGuns[2])
		
	elseif key.KeyCode == Enum.KeyCode.Three and ownedGuns[3] then
		
		equip(ownedGuns[3])
		
	elseif key.KeyCode == Enum.KeyCode.R then
		
		fpsModule:Reload()
		
	elseif key.KeyCode == Enum.KeyCode.F then
		
		fpsModule:Inspect()
		
	end
	
end)

uis.InputEnded:Connect(function(key,gpe)
	
	if gpe then return end
	
	if player.Character then
		
		if key.UserInputType == Enum.UserInputType.MouseButton1 then
			
			fpsModule:Fire(false)
			
		end
		
	end
	
end)
print("printerino 3")
runService.RenderStepped:Connect(function(deltaTime)
	
	fpsModule:Update(deltaTime)
	
end)

Any help is appreciated. (yes, interesting choice of words for printing)
