Have you tried to submit an appeal? I used that a couple of times when it felt like I was bashing my head against a wall and both times the app was approved. Definitely include the originally provided information in your request.

Same here on Chome. (I managed to get in using Safari after lots of refreshing though). On Chrome I'm seeing this error;
Refused to execute script from 'https://appstoreconnect.apple.com/access/static/js/main.b7dc51f4.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled
Hope that helps :)
