We are also experiencing the same issue (we use native script) with our crash logs giving us:

Anyone find a solution yet? What we found is that for older iphones such as anything pre iPhone X we don't experience this only with new models and all in iOS 14. App just crashes immediately and does not log crash.
Edit: Cutoff seems to be iPhones XR and newer do not work
