update: I kinda fix the plug-in problem but now when am going to do my first fight theres another error saying that "Need to be a rectangle" how do I fix this
I think this problem usually affects platforms other than Windows. Recently, a user who emulates the game on Android had the same problem, and so far I have not encountered this problem on Windows, since this game is made for this operating system. Later I will give support to other platforms if the game has support on patreon.
