I cannot add a custom query to a resource

I cannot add a custom query to a resource

There are no query errors, especially for custom queries, and I can add them to resources

However, when I look at the resource list, I do not see the custom query I added.

The request is thrown from Looker Studio to BigQuery, the query is executed successfully, and the temporary table is created!
Why is this?
Please provide prompt support on this issue.
