3. enable node integration in forge config / package.json and browser window / main.js (see package.json and main.js below)
4. npm start
5. Open dev tools / console

Thanks for the bug report but this is not a bug in Electron Forge.

Starting from Electron v12.0.0, the default value of contextIsolation changed from false to true, which prevents use of require in the renderer even if nodeIntegration is enabled. Primarily for security reasons, instead of using require in the renderer, it’s recommended that you instead use contextBridge in a preload script to provide functions to the renderer process instead of using require.

If you need more assistance, please use one of the community forums, including the Electron Discord server.
