Unable to Publish to the App Store

Has anyone else encountered this issue? The app publishes in the system fine, but then it tries to automatically publish to the App Store (it used to require me actually clikcing the button) and then it won’t publish to the app store. I get this error.
I had previously been publishing to the App Store just fine. I even got the app on TestFlight and everything. This feature suddenly stopped working…

Do you have an active Apple Developer account?

Hi Eric. Yes, I have a developer account. I’ve published 8 successful builds of this app to the App Store. It just stopped working. The weird thing is that previously when I would publish the app, it would work, and then I would have to click “Publish to the App Store”. From there it would pull up the window where I would have to enter my credentials and 2FA to log into my dev account, etc. But now, it’s not pulling up that window at all.
