Force restarted my iPhone, and the bug was finally resolved.

I'm also enclosing my FB number in this post. FB16075387

Reported this bug in the Apple feedback assistant as well. This issue is also happening with voiceover as well. It’s really super annoying and I’m a developer beta tester. This is why I submitted my bug report in both the developer forms and feedback assistant.

No work around for this Voiceover bug at this time.

A workaround I found for the bug is turning off your iPhone, wait a little while and then turn it back on again. Deleted all applications and that seemed to stop my iPhone SE 3 from randomly restarting. hope this workaround can help you.
