Depends on the function of the queue. If it's a dead-letter queue, there's literally no downside besides a likely-trivial amount of cost. If the problem is upstream of the queue, and the queue is actively feeding well-functioning consumers, yeah, it could make things way worse. This is where being an experienced engineer comes in. Also having 2-person approval like you would for any code changes. Point still stands that you should take low-risk actions to mitigate if they're available to you before root-causing.
