Github desktop won't open (macOS 11.0.1)

Describe the bug

The app won’t open since installing the latest update (4 Dec).

The app appears to be open in the dock and and menu bar, but the main window is invisible. When I click on “about Github Desktop” , I get the following empty window.

I have access to the developer window, which shows an error:

Version & OS

I’ve tried the latest version linked on https://github.com/desktop/desktop (beta and stable), as well as the latest brew github version: ==> Downloading https://desktop.githubusercontent.com/releases/2.5.6-e0dac138/GitHubDesktop.zip

Steps to reproduce the behavior

1. Launch Github Desktop

Expected behavior

The main window should be visible but is not.

Logs

Logs contain confidential info so I cannot attach.

I’ve tried removing plist files.

Hey @nbara

Yeah I’ve been using Desktop since pretty much the beginning 😃

That’s amazing ❤️

I have a good path forward on a fix for this but given that it’s late friday afternoon and that it looks like this is only affecting a rare subset of users who have been using the app for a very long time and who have also been using the beta version of the app I think we’re going to have to wait until early next week with a release to fix this.

I have two options for you, either you delete the ~/Library/Application\ Support/GitHub\ Desktop folder and start fresh (you’ll have to sign back in again and add your local repositories).

Or you take a backup copy of the same folder and copy and paste the following hack into the DevTools console of the app

indexedDB.open('Database', 70).onsuccess = event => {
  const db = event.target.result
  const tx = db.transaction(['gitHubRepositories'], 'readwrite')
  const objectStore = tx.objectStore('gitHubRepositories')

  objectStore.getAll().onsuccess = event => {
    const repos = event.target.result.filter(x => x.parentID === undefined)
    const putNext = () => {
      const repo = repos.shift()
      if (repo !== undefined) {
        console.log(repo)
        objectStore.put({ ...repo, parentID: null }).onsuccess = putNext
      }
    }
    putNext()
  }
}

That script should take care of finding that stray repository and fix it up. Once you’ve run it you can relaunch the app and it should work.
