✖ Validate packages against React Native Directory package metadata
The following issues were found when validating your dependencies against React Native Directory:
  No metadata available: @mobile-wallet-protocol/client, @mobile-wallet-protocol/wagmi-connectors, expo-standard-web-crypto, viem, wagmi
Advice:
Update React Native Directory to include metadata for unknown packages. Alternatively, set expo.doctor.reactNativeDirectoryCheck.listUnknownPackages in package.json to false to skip warnings about packages with no metadata, if the warning is not relevant.

✖ Check that packages match versions required by installed Expo SDK
The following packages should be updated for best compatibility with the installed expo version:
  react-native@0.76.5 - expected version: 0.76.9
  react-native-screens@4.10.0 - expected version: ~4.4.0
Your project may not work correctly until you install the expected versions of the packages.
Found outdated dependencies
Advice:
Use 'npx expo install --check' to review and upgrade your dependencies.

npx expo install --check reports the same.
