Yes, I use the main menu plugin of Visustella, there I put the command line that you put in the description of the plugin to enter the interface, will that be the problem? I use your other plugins like this too and they don't give me problems

I'm not too sure, as I am unable to reproduce the problem in my test project. If you want, you could send me a sample project with just [CGMZ] plugins installed that has the problem so I can take a look at it. You can send me a DM over discord with a link to download the project with the issue.
One thing you could try is to paste this into the bottom of the plugin's .js file, but it might just make the error occur at a different place:
CGMZ_Window_ReputationList.prototype.item = function() { return (this._data) ? this._data[this.index()] : null; };
