Describe the bug
So I gave up on trying to install windows on my iphone, due to storage limitations, but still reinstalled altstore after a while, just to check out the new features. I get respring loops all the time, and I thought it was a bad tweak
What was weird was that whenever I would install UTM, whether it was from altstore or filza, and then try respringing, it would enter a loop. I don't know for sure, but I am pretty sure that UTM is the cause of this

To Reproduce
Steps to reproduce the behavior:

  1. Install UTM
  2. Close UTM from app switcher (i.e. crash it)
  3. Respring
  4. It gets stuck in a loop

Crash log
There is no way of getting any logs, as it is in a state where springboard is broken

Maybe you close UTM without clicking X button.
This will cause #32, and respring loop (in jailbroken state) so you should force restart it.
In this state iDevices cannot shutdown itself and will try to reset.

I've heard of this issue from a few people now but only people who are jailbroken. My suspicion is that something else is the issue here. UTM is a sandboxed app so if it's able to crash the OS, then we found a 0day sandbox escape.

Yes that is what I was trying to do, I was seeing what happens if you respring after the crash, or ldrestart, but no you have to reboot completely to run utm, which is annoying on checkra1n

@SarKaa I think if you have Mac you can use Apple configurator 2 to see the console and log it but you have to have password off.
