So, to summarize

In main/index.dev.js:

- require('electron-debug')({ showDevTools: true });
+ // NB: Don't open dev tools with this, it is causing the error
+ require('electron-debug')();

In main/index.js in the createWindow() function:

mainWindow.loadURL(winURL);

+  // Open dev tools initially when in development mode
+  if (process.env.NODE_ENV === "development") {
+    mainWindow.webContents.on("did-frame-finish-load", () => {
+      mainWindow.webContents.once("devtools-opened", () => {
+        mainWindow.focus();
+      });
+      mainWindow.webContents.openDevTools();
+    });
+  }

I had simliar issue

with yarn (1.2.0) (yarn && yarn run dev)

---

surprisingly, with npm install && npm run dev, everything works fine (^^??) So if there is someone who suffers problem like me, try to use npm instead of yarn.
