Issue: I downloaded the launcher. When I click run it says 'failed to read configured distribution'. It does not allow me to do anything at all. I've tried redownloading it and that hasn't work

Console Output
68747470733a2f2f696d672e736869656c64732e696f2f6769746875622f72656c656173652f647363616c7a692f456c656374726f6e4c61756e636865722f616c6c2e7376673f7374796c653d666c61742d737175617265:1 Failed to load resource: the server responded with a status of 504 (Gateway Timeout)

Hopefully this is a simple issue and I'm just being dumb about it, but any advice would be appreciated
