I encountered an error where multiple ad groups were created without ads or keywords.

This usually indicates that the publishing process did not complete. Here are two steps you can take to resolve the issue:

1. Try publishing again: Sometimes re-initiating the publishing process resolves the issue if there was a temporary interruption.

2. Use Google Ads Editor: If the issue persists, try publishing the ad groups via Google Ads Editor as a workaround.
