Solution
Personally I have tried to upload the same build 3-4 times to App Store connect through Xcode, 4th time app got uploaded! Hope it helps you too.
Here’s another workaround I got from StackOverflow:
- 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 !
Reference: What is an error analyzing app version when distributing from Xcode?

Happy Coding 🙂
