iPhone 11 wont open apps or power off

Thanks for reaching out for help on the Apple Support Communities JustinB725,

We understand you're having some trouble powering your iPhone off, and opening apps, and we'll be happy to help.

If you press and hold the side button on your iPhone, does the power off slider appear?

If not, or the slider is unresponsive, use the guidance from the following page to force your iPhone to restart: If your iPhone, iPad, or iPod touch won't turn on or is frozen

Regarding apps on your iPhone, if the behavior persists after restarting, try the steps found here to address the behavior: If an app unexpectedly quits, stops responding, or won’t open

We hope this helps!
