Version 10: Your configFile is invalid cypress.config.ts

Current behavior

I can’t get by this screen after the cypress UI pops up, everything seemed fine until the config->.ts step.

Error
Your configFile is invalid: C:\Github\Project\cypress.config.ts

It threw an error when required, check the stack trace below:

OK so first of all it looks as if the specific ERR_UNSUPPORTED_ESM_URL_SCHEME stack trace I was seeing only appears with Cypress 10.0.0. In 10.0.1 I believe this behaviour may have been slightly altered, and I now see a different error. Specifically, this issue. I will take a look at that issue and see if I can add anything useful there instead. This issue can stay closed.
