when does a message queue start causing more problems than it solves

hey everyone, ive been thinking about message queues lately. we use them for a few critical background tasks, and theyve been fantastic for decoupling services and handling spikes. but im wondering, when does the complexity of setting up and managing a message queue outweigh the benefits? are there simpler patterns for asynchronous tasks that dont require a full-blown queue system? curious to hear your experiences and thoughts on this.
