App Crashing On Certain Devices After iOS 14 Update

We recently became aware that some of our users are unable to launch our app after upgrading to iOS 14. After doing some testing today, it seems that on newer devices (iPhone X and 11) it crashes immediately. However, on older devices (6, 6s, and 7) it is working like normal. It only seems to effect newer devices after they upgrade to iOS 14, but not older ones. Has anyone else experienced anything like this since upgrading?
I'm on IOS 14. Something. Its March 2021 and it's still crashing immediately.
