Stuck on launch with Debug

Attempting to run my app on the simulator or device seemingly leaves it stuck on the launch screen for a long time. Slowly, the terminal will start to relay info suggesting it's past that but still displays the launch screen until eventually it goes to a black screen. No changes I am aware of were made to cause these behavior to start. And it was a sudden issue. My last OS update was a few days ago and my last Xcode update was after this started to occur in hopes it would fix the problem. Recent code changes would have nothing to do with startup. I did try to delete derived data and ~/Library/Developer/Xcode/iOS DeviceSupport/ based on solutions given to other users with similar problems. I've restarted the computer and cold restarted. When I stop the application from Xcode, I can then run the app. It's just when it's attached. It will also work if "Debug executable" is off. Other apps on this computer do not seem to have this problem. Would appreciate any help. Thanks.
