Looks like you removed a default setting from AEM (the service-user-mapping for this bundle). If that's a lower environment, I would suggest to rebuild it from scratch.

If you cannot afford that but need to fix it, you should check the OSGI configuration manager for the string "design-cache-service" and compare it with an instance where this error does not appear.
