The plugin only works in RPG Maker, but if you make a game package, the game just takes a long time to load and nothing happens, even on a completely empty project.

Yeah, I've warned about this before on a comment below (I should've include it on the page haha).
You need to manually add back all assets that you were including via this plugin.
It's the workaround for now, sorry! I know the fix but do not have the time to edit yet. Hopefully can update around holiday.
Also, can you show me the error message when you press f12 and go to console tab?
