Hey @andrey,
This is indicative of some error in your JS code. Prior to SDK35, we used to handle fatal crashes by displaying the blue Expo error screen but users made it known that they would prefer a hard crash rather than an Expo interface so we made the change recently. Standalone apps should hard crash rather than show Expo error UI · Issue #4230 · expo/expo · GitHub
I would recommend setting up Sentry or some other JS-error reporting service to get better insight into what is causing your crash(es).
Cheers,
Adam
