Yes, I know that you can just disable this plugin, but I’m wondering why this error appears and how to fix it. Everyone usually has an error of 0, but for some reason I have 37, I want to know what this error means and how to fix it and not get rid of it.

Not sure. You’ll probably be better off contacting Epic Support.
