Create UWP app package: The store blocked this account. Ensure the account has permission to read reserved app name...

Hello, I have developed an UWP app and try to publish it to Microsoft Store., Reserved a new name for app and created app submission in Microsoft Partner Center.

Now I'm trying to create app package for deploying to Microsoft Store in VisualStudio 2022. I choose Project-Publish-Associate App with the Store.. or Project-Publish-Create App Packages-Microsoft store under a new app name. In both cases I see "Select an app name" dialog and error message instead of list of existing app names: "The store blocked this account. Ensure the account has permission to read reserved app name and that it is linked to a valid Developer subscription."

I have checked my Microsoft and Microsoft Partner Center account settings and can't find that my account blocked. Could you please help me what should I do in this case?
