iPhone 17 Pro Max unexpectedly shuts down and restarts on iOS 27 with Lockdown Mode

Hello, I’m on iOS 27 with Lockdown Mode enabled on an iPhone 17 Pro Max. A few minutes ago, I was downloading GIFs from Giphy and editing them when my phone suddenly shut off and showed a loading/spinning icon. After a few seconds, it came back to life. This happened about three times before I did a force restart and closed out some apps in the background. It hasn’t happened again since. I Just wanted to check to see if it is a bug/glitch or something I should be more concerned about.
