I checked the release log file "IDEDistributionAppStoreConnect.log" I found that the api url（https://appstoreconnect.apple.com/iris/provider/xxxxxx/v1/apps?xxxxx） was unable to retrieve my application information. I logged into my developer account in the browser and manually opened the link in the browser, which returned the information of the app I tried logging out of my account in Xcode, logging back in, and resubmitting the operation, but the same error occurred. Just to clarify, my account also has APP administrator permissions under another company's account. I'm not sure if this has any impact.

The issue is indeed related to "my account having administrative permissions under another company's account". My personal account has been assigned "administrative" permissions (with the authority to manage certificates) under another company's account. Yesterday, I tried to remove my account from that company's account. Today, when I tried to package and submit, Xcode prompted me to access my certificate (presumably the certificate for my personal account). After I agreed, everything proceeded smoothly. It seems that when my account has administrative permissions for multiple accounts, Xcode uses the wrong certificate.
