Not able to delete existing device in Community Edition Control Room AA360. Error:- Device is part of Active Deployment (no tasks are running although)

Tried these things to resolve the issue-

1- Uninstalling Bot agent and deleting Device from CR

2- Reinstalled Bot agent and tried to add device (throwing error only 1 device can be added although device already present is in disconnected state)

3- tried restarting Bot agent services

Nothing worked till now, Please suggest/guide me to resolve the issue.

Thanks and Regards,
