Hi @sooyeon_Lim

Ensure that you are synchronizing access to the collection when multiple threads or activities are modifying it simultaneously. In UiPath, you can use the “Invoke Workflow File” activity with the Isolated property enabled to execute a workflow in a separate workflow environment, which can help with synchronization.

Thanks!!
