i have no encryption tables.

looks like it’s a known bug: [Warning message about keyring component metadata query service in error.log](https://forums.percona.com/t/warning-message-about-keyring-component-metadata-query-service-in-error-log/11892)

Still active in 8.0.32 too : [https://bugs.mysql.com/bug.php?id=103684](https://bugs.mysql.com/bug.php?id=103684)

i can reproduce the bug with this simple select :

```auto
SELECT * FROM performance_schema.keyring_component_status;

```
