Im new to modding for stardew valley and when I boot up the game, it gives me an error saying I have multiple copies. I searched around, but can't seem to find them. If someone can help me I would very appreciate it!

It says you don't have the Error Handler mod installed. Try reinstalling SMAPI and see if that fixes it.
