# Erro Expo Uncountered a fatal error

Hi somebody can help, i’m builded my app in a Bundler mode and i got this error:

So well a just clean my app data in phone and all be okay !!

So this is resolved for me!

I am interested to know what SDK version you are using?

This is my ambient

Expo CLI 3.24.0 environment info:
System:
OS: Windows 10 10.0.19041
Binaries:
Node: 10.14.2 - C:\Program Files\nodejs\node.EXE
Yarn: 1.16.0 - C:\Program Files (x86)\Yarn\bin\yarn.CMD
npm: 6.4.1 - C:\Program Files\nodejs\npm.CMD
IDEs:
Android Studio: Version 4.0.0.0 AI-193.6911.18.40.6626763
npmPackages:
expo: ^38.0.0 => 38.0.9
react: 16.11.0 => 16.11.0
react-dom: 16.11.0 => 16.11.0
react-native: https://github.com/expo/react-native/archive/sdk-38.0.2.tar.gz => 0.62.2
react-native-web: ~0.11.7 => 0.11.7

Hmmm… I have seen this sort of error caused when an OTA update does not download correctly, but that was with earlier SDK versions. I haven’t tried to reproduce it with SDK 38 before. I was hoping that with the recent changes to the Updates code that this would have been fixed.

Here’s a comment from me about this along with a link to something that seemed to fix it for me:
