Hi @Pravin_Mandadi ,
Could you make sure if you have followed the Best Practices mentioned in the document for Orchestration Process (Create Validation/Wait For Resume activities process) :
https://docs.uipath.com/studio/standalone/2023.4/user-guide/orchestration-process#best-practices
Do check for any other type of variables used in the Main workflow (Also the Enclosing Sequences where the Wait for Resume activity is used) and change its scope.
