Hello,
I'm currently running a unity app on HoloLens 2 for my graduate research. But sometimes, the app closes unexpectedly that the user needs to click on the window to reopen it. I already turned off the screen sleeping function. But the problem still happens occasionally such that it is extremely hard for me to keep the app run for more than 15 minutes.
I find out sometimes it happens when I flip up the lens over 3 mins. But I'm not sure is there any factor that will cause this issue.
Many thanks!

It sounds like the app is crashing, and you'll have to debug it to find out why.
If you can reproduce this live under the debugger then that's the easiest way to debug. See Debugging an installed or running app. If it doesn't repro under the debugger then you can probably generate a crash dump. See App Crash Dumps.
I see that you've also opened an assisted support case for this, so a specialist will be able to work with you on this one-on-one.
