Apparently you should use the false exit of the "Check Asset Register" IF block to create the "next" task you planed, if there are only two cases. You may use "switch block", if the false exit of IF block is confusing.
I misunderstood you last time; not sure if you have figured out a solution, but I believe what you want to achieve should be done at the parent service request level. So basically when a team completes a task created by the workflow, they also need to "indicate" if there is an issue by setting a value on the task form before they set the task to Complete. At this time, the task and workflow execution are done, but the service request isn't fulfilled and a business rule can decide, based on the team updated service request field value from the task form, if the workflow should be triggered to create another task automatically or send communications to the customer or fulfill the service request.
