Reproducible demo or steps to reproduce from a blank project

1. Create blank project with npx create-expo-app -t expo-template-blank-typescript (make sure SDK49 is used)
2. Add this to your app.json

   {
   "expo": {
   "experiments": {
     "tsconfigPaths": true
   }
   }
   }

3. Run npx expo-doctor

Hi @stefan-schweiger! As you mentioned, the tsconfigPaths was added since SDK 49. SDK 48 doesn't have this, and somehow that's exactly what expo-doctor has detected in your project:

If this is still an issue on your end, please open a new issue (with repro) on the expo/expo repository.

Hope this helps!
