Just here to say we are experiencing this too seemed to have started this morning after 11am EST

Thanks for opening this issue detailing the error. I've escalated this to our API team to investigate. Sorry for the inconvenience.

[bvanderneut]

Any progress on this? It's almost a day now that we cannot use the dashboard and we need it to test stuff to go to production.

Our engineering team has released a fix for this issue - of seeing the Cannot read property 'name' of undefined error when running in Windows OS's. This fix should be immediate and not require a new version of Cypress.

Please comment here or open a new issue if you continue to see this issue on any new runs that are recorded to the Dashboard.
