Interactive Installation Quesitons

Hey All!
I was wondering if anyone has had any experience using unreal in installations that run 24/7. Im coming from the 3d animator world and slowly moving into creating more interactive pieces for real world spaces. But Im uncertain if it is realistic to expect an unreal project to run constantly. With that, im uncertain if other programs like touch designer, notch, or unity run without hiccup. Are there standard ways to navigate crashes and restarts, or are things so stable and optimized that its not an issue ? In my brain, they are all softwares and so eventually will crash, but Im not very experienced in actually deployment and hardware. I can create things, i just want to be realistic of how things can be used. Would love to learn if anyone has any insights. Thank you!
