There are several reasons a nested stack could be stuck in an UPDATE_ROLLBACK_COMPLETE_CLEANUP_IN_PROGRESS state. These are;

  1. CloudFormation is still in the process of removing old resources, or can't remove those resources due to a dependency issue.

  2. Resource cleanup is paused because a sibling stack of a nested stack fails to update or roll back.

For troubleshooting steps, see our detailed knowledge center article Why is my CloudFormation stack stuck in the UPDATE_ROLLBACK_COMPLETE_CLEANUP_IN_PROGRESS or UPDATE_COMPLETE_CLEANUP_IN_PROGRESS state?
