I can contact support but I'm still getting this error.

Same here, and i don't have a version appear in the appstore connect page. it's just throws this error i have no idea why.

Suddenly stopped working with this exact error. Do we just wait for apple to fix it on their side?

Has anyone found a solution to this problem? I'm also not able to push a build to app store. I get an email from apple with the following: Dear Developer, We identified one or more issues with a recent delivery for your app. Please correct the following issues, then upload again. Best regards, The App Store Team No information is given on the issues, though?
