I'm getting this error on some of the workflows.

all the Users in the User Group added with Full Control, some of them not able to receive any notifications when they create an item and when I see the history of the workflow the Task in the workflow is throwing this error, but when I create an item with my login, I’m able to receive the Task assign notification etc..
Any Idea why it's doing that?
