WORKING BYPASS: While Apple's Hardcore Software engineers drink coffee and figure this bug out! Organizer -> Distribute App -> App Store Connect -> Export -> NOW DISABLE WIFI / INTERNET (else will fail) -> Exported .ipa Now use Transporter App -> Login to same account -> Add .ipa -> Upload works ! Transporter Can be downloaded from AppStore

Still down, seems like servers are overloaded, got through at one point, then API requests for this API key in the past 60 seconds, now back to old error as OP.

Worked for a moment then crashed again

Yeah best luck apple engineers !
