Module script Pcall stops abruptly?

My code is a session storing module script which stores data such as in-game money. I can edit these values through the module scripts from other scripts etc

My code for saving data is triggered by when the player is leaving the game.

game.Players.PlayerRemoving:Connect(function(Player)
	print("Player removing")
	local Key = Player.UserId
	print(tostring(Key))
	local Success, Error = pcall(function()
		PlayerData:SetAsync(Key, SessionStats[Key])
	end)
	print("pcall done")
	if Success then
		print("Saved")
	else
		warn(Error)
	end
end)

My code works up until the point when the pcall ends, and "pcall done" never prints or outputs.

I can see nothing immediately wrong with what I've done but any help is appreciated.
