Interactive debugging tends to be unhelpful on anything realtime. By the time you look at what's going on, all the timing constraints are shot and everything is broken. You may be able to see the current state of that thread at that moment, but you can't move forward from there. (Unless you freeze all the threads - but then, all the threads involved might not be in one process, or even on one machine.)
I’m not negating that. But in most cases, using a debugger is the vastly superior way to debug issues, yet many developers have never bothered to pick up on that knowledge. Like a carpenter that hasn’t ever learned to work with power tools and insists to use manual screwdrivers for everything.
