Hello,
My Expo apps are crash on launch. even I try with the older code of my apps which was working perfectly on when I publish the code but now that code is also not working. Any help !!

Thank you,

hi! sorry to hear your app is crashing, we wrote up a guide on debugging production crashes here- https://docs.expo.io/workflow/debugging/ - hopefully that helps you investigate a little bit more

Thank you @charliecruzan, I’ll try with Expo-sentry to find the problem.

Hello @charliecruzan i tried sentry as mention in document, But i’m able to find any error.

for production app crashes:

  • Access the native device logs
  • Reproduce the crash (either using your production app, or the Expo client app)
  • Search the logs for a “fatal exception” (there could be a few) to see exactly what is causing your app to crash
