navigation.navigate does not recognize "savePost" screen

[landingburn]

What the terminal says when I try to bring a video into the application I'm making is that Do you have a screen named "savePost" This is where I am trying to navigate
return ( <NavigationContainer> <Stack.Navigator> {currentUserObj.currentUser == null ? <Stack.Screen name = "auth" component = {AuthScreen} options = {{headerShown: false}}/> : <> <Stack.Screen name="home" component = {HomeScreen} options = {{headerShown: false}}/> <Stack.Screen name="savePost" component = {SavePostScreen} options = {{headerShown: false}}/> </> } </Stack.Navigator> </NavigationContainer>
This is the part where I use navigation.navigate, i tried navigation.push and to navigate without the useNavigation() both did not work.
`const pickFromGallery = async()=>{
let result = await ImagePicker.launchImageLibraryAsync({
mediaTypes: ImagePicker.MediaTypeOptions.Videos,
allowsEditing: true,
aspect: [16,9],
quality: 1
})
if(!result.cancelled){
let sourceThumb = await generateThumbnail(result.uri)
navigation.navigate("savePost", {source: result.uri, sourceThumb})
}

}I can put the SavePostScreen code here as well, but I doubt it will do anything, I am just putting the package.json file here. "name": "academical",
