After updating Unity from 6000.0.11f1 to 6000.0.20f1, iOS upload process fails

Hi!

I’ve updated Unity Preview from 6000.0.11f1 to 6000.0.20f1 and I get this error on the iOS upload process to Appstore connect.
Compilation works, but the upload verification fails.
To be sure, I rollbacked to 11f1 and did the same, and the upload went through successfully.
And after updating again that same project to 20f1, the same error appeared.

This is the error:

Could this be a regression issue from Unity 20f1?
Any help will be appreciated.

How do you get 6000.0.20f1. The newest version is stlil 6000.0.19f1:

Can’t see anything named ‘unity-plugin-library’ in source, so I doubt it is ours. Could be some plugin in your project?
If you don’t mind, could you check some more versions? i.e does 16f1 also fail? Would maybe help me check for potential changes

There’s a public link in another thread.

Will try that, thanks a lot. Sorry for the inconvenience.
