Elastic Endpoint failed

I am running elastic v8.13 on linux machine
I am trying to monitor K8S cluster (SIEM - FIM and EDR)
the agent is installed and I can get all nodes, then I added the system and FIM integration with no issues, the issue happen when I am trying to add Elastic Endpoint security integration, it fails with error

failed install endpoint service error:Util.cpp:92 Service ElasticEndpoint already exists:exit status 21

Can anyone advice how can I troubleshoot or the root cause of the issue?
