HTTP ERROR 503 AuthenticationSupport service missing. Cannot authenticate request.
We are using Adobe Experience Manager 6.5.17.0 for our development. The team frequently facing an issue with error message
"20.10.2024 07:44:04.286 *ERROR* [qtp1932271856-175] org.apache.sling.engine.impl.SlingHttpContext handleSecurity: Possible reason is missing Repository service. Check AuthenticationSupport dependencies.
20.10.2024 07:44:04.288 *ERROR* [qtp1932271856-89] org.apache.sling.engine.impl.SlingHttpContext handleSecurity: AuthenticationSupport service missing. Cannot authenticate request.

To resolve this error we usually will follow the steps as below:
1.Stop the AEM instance.
2.Delete the following files:
/publish/crx-quickstart/repository/segmentstore/repo.lock
/publish/crx-quickstart/launchpad/felix/cache.lock
/publish/crx-quickstart/repository/index
/crx-quickstart/launchpad/config/org/apache/sling/jcr/repoinit
Restart the AEM instance.
Even these steps not helping us to login the AEM system. We are getting the error message as below :

We could access the configuration Manager with admin credentials in browser. If we cross verified the Granite Authentication Handler, that bundle is active only.
We noticed the bundle "Adobe Experience Manager Graph QL for Content Fragment scq-dam-cfm-Graph QL" is in installed state and we couldn't change that to active state.
Is there any relationship between these error and this Graph QL bundle? can anyone suggest solution for this issue?
