What were you trying to accomplish when the crash occurred?

I had just forked https://codesandbox.io/s/introduction-to-jsx-h8ub1?fontsize=14&module=%2Fpublic%2Findex.html%20babeljs.io and tried to Sign in clicking on the top right corner. I selected my Git hub account, agreed to the terms (sharing my email), then whe I clicked I got the crash screen.
