CodeSandbox crashed on log-in

💥 Crash Report

What were you trying to accomplish when the crash occurred?

I was in the middle of editing a project in CodeSandbox while not logged in. I then attempted to log in with my github account. I hadn't used CodeSandbox before, so I needed to allow access. After completing the process, I saw the "Oh no, something broke!" page.
