Error: Extension server error: Object not found: <top>

Error:

• I build the app with npm build
• If I run npm build, everything works fine
• However, if I run npm dev, I get the following error:

┏ Electron -------------------

  [6736:0523/215626.854590:ERROR:CONSOLE(1)] "Extension server error: Object not found: <top>", 
   source: devtools://devtools/bundled/extensions/extensions.js (1)
  
┗ ----------------------------

• The GUI is just frozen, I cannot do anything, sometimes not even all chess pieces are loading

Problem:

• This is a well known problem and should be an easy fix.
• See this comment Chrome Dev-Tools error? SimulatedGREG/electron-vue#389 (comment) for example.
• devtools needs to be initilized after the mainWindow has been loaded, but not before!
• I could reproduce that this is indeed the problem, by uncommenting debug({ showDevTools: true }), hitting save, readding the line, hitting save again, all while the "frozen" LiGround window was open, which in the end let me use LiGround in dev mode again.

Thank you for the fast reply! Sadly the suggested change did not fix the problem, but the error message changed for now:

  ERROR in ./src/main/index.js
  Module parse failed: The top-level-await experiment is not enabled (set experiments.topLevelAwait: true to enabled it)
  File was processed with these loaders:
   * ./node_modules/babel-loader/lib/index.js
  You may need an additional loader to handle the result of these loaders.
  Error: The top-level-await experiment is not enabled (set experiments.topLevelAwait: true to enabled it)

It has still the same behavior: if I change some code, the app automatically reloads and is working fine!
