Only way that could happen is if your project config is somehow missing its users key. I’ve updated the template to make it more defensive about that, for the next release.

To get the fix early, change your craftcms/cms requirement in composer.json to:

"require": {
  "craftcms/cms": "dev-develop#30b4b1c351cbc24b26cf54b91bb06a9af71f004c as 3.1.25",
  "...": "..."
}

Then run composer update.
