I have published an external Google Spreadsheets addon, and everything worked so far. Since a couple of days, within the "Google Cloud Platform > APIs & Services > G Suite Marketplace SDK > Configuration panel" the input field for "Sheets add-on script version" is empty and an error message "At least one extension must be enabled and selected extensions must be configured" is displayed.
I have already tried the following steps:
The response is the following:
Error Sorry, there’s a problem. If you entered information, check it and try again. Otherwise, the problem might clear up on its own, so check back later.

The problem did not clear up so far and also the Google Support team did not reply to my feedback/message so far.
Due to this behaviour I am not able to publish new versions.
I work in the G Suite Marketplace. This issue has been fixed and it will roll out to production between today and tomorrow.
