I am trying to release an app from Xcode but as soon as I try uploading to the app store or exporting in any fashion, once it checks for signing from iTunes Connect, I recei
In my case, the problem gone away when I've re-added my account in Xcode > Preferences > Accounts and both logged out/logged in in the Mac App Store. I was checking my sandbox user and right after that Xcode began to say my session is expired. Hope this will help to resolve your issue.
In the end, finally resolved by calling apple support and getting elevated to upper level tech, where eventually we discovered missing shared folder in /Users. Adding a shared folder resolved my issue. Here’s the steps to reproduce solution if it applies to you:
Finder > Go > Go to Folder
enter /Users :: Go
if no Shared folder, open Terminal to create one in /User
Enter commands in Terminal (must be logging in as user with admin access):
sudo mkdir -p /Users/Shared
sudo chmod 1777 /Users/Shared/
reboot and see if can now login

For Xcode 11 and Big Sur, I got official email from Apple saying that "From your email I can tell that a possible reason for you seeing this error message is the fact you are on the live version of Xcode and the. Beta version of MacOS. What I would suggest doing is updating the the Xcode version so it will better communicate with the MacOS. Please see the below link for more information on Xcode 12 beta."
The session of one of my accounts (not even the one I was trying to use) had its session expired. This seems to be new. I just had to re-sign in to the errant account in Xcode > Preferences > Accounts.
In my case, Apple were trying to force me to update my profile / password. Try signing into https://appleid.apple.com/account/manage first.
Discovered this while trying to enable Two-Factor Authentication so thanks to Hiran for his suggestion.
I had the same issue after changing the APPLE ID password.
Go to: xcode> preferences>account> sign in again
