We are facing an issue after creating workflow and childs are not getting created.  
Our current temporal sdk version: 1.19.1  
Temproal Server version: 1.22.0

WorkflowTask: failure executing SCHEDULED-\>WORKFLOW\_TASK\_STARTED, transition history is [CREATED-\>WORKFLOW\_TASK\_SCHEDULED]

Potential deadlock detected. Workflow thread “workflow-method\_XXXXXXXX” didn’t yield control for over a second.
