I have a new app just released the last couple of days. The app ONLY crashes when downloaded from the App Store. App Analytics does not show the crashes and only says there is not enough data. Anyone have any suggestions on how I can track this down? Without some kind of crash log I don't even know where to start.
You'll be fine...now is a good time to learn how to use crash logs 😉
If you haven't already, see;

I should add it seems odd it didn't do the same for App Review as it does in your case.
If you believe this is affecting users in the wild, you may want to temporarily take it off sale in all countries until you can sort things out.
