How has this issue affected you? What are you trying to accomplish?

Can not use VS Code so I can not try out your service to determine if I want to pay for it.

Start by reproducing the sign-in flow from the VS Code extension using GitHub or Google, as described in the issue, and inspect where the account-creation restriction error is returned. The issue names no source file or test; done means users can complete sign-in without receiving the codesandbox.io email restriction error.
