iOS App Exists after launch

Hello, my iOS apps are exiting right after launch on a few of our iOS devices. I tried a couple of my apps that are deployed to our fleet and they do the same thing. If I run the app(s) in the Simulator it works fine and if I run the app(s) on the offending devices it works fine as well. Once I stop the run in Xcode the app on the device will not launch.

I'm thinking something is missing like a certificate etc. Just not sure.

Any ideas on how to troubleshoot this? I would really like to get this fixed.
