I find that when my laptop goes to sleep for longer than 15 minutes or so, when I wake the computer and log in, PowerApps will display a solid purple screen for several minutes before silently crashing.
I didn't encounter this issue before. This kind of crashing issue could be caused by so many random reason, it is hard to track the root cause. PowerApps will autosave your before work and can recover it next time you open it. So I suggest that you can close PowerApps next time if you leave for a long time.
