Xcode 12 cannot upload archive to App Store Connect

Hi,

I am running macOS Big Sur Beta 11.0(20A5384c) and Xcode 12.0.1(12A7300). When I try to upload an archive to App Store Connect for distribution, it always gives me a warning message:
App Store Connect Operation Error
Could not find or load main class
Du.Library.Java.Extensions:.Library.Java.Extensions:.Network.Library.Java.Extensions:.System.Library.Java.Extensions:.usr.lib.java:.

The same message appears when I use altool to upload to App Store Connect.
Apple Transporter would not even start up, and in the error log it states the same message.

When I look into my /Library/Java/Extensions/ , nothing exists in that folder
I have the latest version of JDK (15) and JRE(8u261) installed.

Anyone has the same issue or knows a workaround? Any help would be appreciated.

Sounds like the backend is acting up (you're apprently not alone). Be patient and try again later.
I'm having the same problem but on Catalina.
I'm having the same issue, any update on this?

Catalina 10.15.6
Xcode 12.1
I'm having the same issue too.

xcode 12.1
macOS Catalina 10.15.7

The warning info is "***" iPhone is not available. Please reconnect the device.

Any one can help me?
