Error with metro bundler when running npm start

error with start npm start in react native can’t start my project.

Hi.

Is this a new app or an existing one? Based on the directory name it looks like a new one?
Did you by any chance recently update the above regex pattern? I’m not sure what that is being used for but it seems to be using Windows filename separators (backslashes) when it should probably be using slashes (/) instead. Or do you get this error immediately after using expo init to create a new project and then running npm start?

Also, could you please run expo diagnostics in the E:\my-new-project directory and then post the output as text here like this:

```
