This started off appearing after deploying an OTA update to Android and preventing the app from loading (crash on boot), but has since started occurring with the app running. ANR report (as does a logcat) reveal the following error:

com.facebook.react.common.JavascriptException: Error: Expo native runtime is not available: something went wrong and we aren't sure what it was. Please post more information and get support at, stack:

this only happens on Android; iOS appears completely fine. I’ve got no idea where to keep looking… it’s super frustrating! I’ve been over the entire codebase several times and not spotted anything that feels suspicious. I think it started happening around SDK40.0.0 but can’t be 100% sure.

App is deployed via the Google Play store.
