I’m a software engineer as well. We had a guy who was demoing some test software a few years ago and he had an unhandled exception that crashed his program. My team lead told him to get the information and fix the bug and he said that it was “a one time thing.” We still laugh about it today. If it happened once, it will and can happen again.
It's amazing how turning something off and then back on again can solve most issues in tech. :D
