Classes break in the npm version but work on the web version

Describe the bug:

The program crashes when using the npm module but works when using the website.

Config and Small code sample

Config:

{
  target: "node",
  preset: "medium"

Code:

const Discord = require("discord.js");

/**

            }),
        });
        this.token = token;
        this.login(token);
    }
}

module.exports = NeoBot;

When starting the code obfuscated with the npm module, I get an error saying:

TypeError: Cannot read properties of undefined (reading 'js')

While the web version seems to work just fine.

Classes break in the npm version but work on the web version #130
