Redshift serverless snapshot status creating never finisher

Good day Everyone. I am trying create a new manual redshift server snapshot using databackup board, however the backup never ending, still in status creating and size = 0. I cannot delete, or do anything, unless change the retention time.

I already check conectivity, limits, resources and logs, and did not find anythng unusual or errors.

In the same account another namespace/group the backup is normal.

I think in create a new grp/namespace, export/import the data, however this is not a easy solution, either answer the que question why thi is happen.

Any thoughts, suggestions? Thankyou in advance
