type and metro errors

[MelihaDuman]

I am using expo app for my project and keep getting this error

ERROR TypeError: Cannot set property 'intArrayToUtf16' of null, js engine: hermes
ERROR Invariant Violation: "main" has not been registered. This can happen if:

• Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
• A module failed to load due to an error and AppRegistry.registerComponent wasn't called., js engine: hermes
