Sourcemap issue

[Fractal-Tess]

Hey there

I have a problem with sourcemaps - similar issue to (#368)[https://github.com//issues/386].
tl;dr, I wanted to store some variables on disk, so I installed electron-store and exposed some functions in the preload package.
However, this causes a bunch of sourcemap errors in the console of the application.

To replicate, clone this project and and electron-store, followed by adding this code to the index.ts file of the preload package:

import ElectronStore from "electron-store";

const s = new ElectronStore();
s.set("v", 1);
export const store = () => {
  return s.get("v");
};

Now, regardless if this function is used or not, the startup of the application is considerably slower, not to mention all of the sourcemap missing warnings.

Any recommendations?
