How to modify someone else's game on RPG Maker MZ?

[DbatRT]

Hi, I want to make a mod for a finished game (Dragon Conquista) on RPG Maker MZ, I tried to open the game editor but I got an error: Unable to read file plugins.js.

So, I would like to ask how is it usually done and is it possible to do it?

Sounds like it's a corrupted file/plug-in of sorts
