Watch app works fine in Simulator but crashes on Watch

My app crashes as soon as I try to launch it from my Watch, even though it works completely fine in various simulators. How do I go about finding out what is causing it to crash?


Note that I've had my app run on my watch before, but all the iOS/WatchOS/Catalina updates as late caused an issue where I couldn't install my app to my Watch. After the latest update I can still it to my watch again except it just crashes on startup.
