Have you been able to find a solution to this problem?

Hey, I am not able to reproduce this issue on a fresh app, but this seems to be an issue relating to the @rnmapbox/maps. This issue (https://github.com/rnmapbox/maps/issues/3193) seems related, so maybe start there to try and debug it. This (https://github.com/rnmapbox/maps/issues/3193#issuecomment-1902529788) could be a possible solution. Let me know if you find anything.

One thing I would also try is to remove @youssefhenna/expo-mapbox-navigation and work on getting @rnmapbox/maps working on its own first, so that we can pinpoint where the issue is coming from.

Hello Again. I got the solution for this problem.

I actually forgot to add these plugins in my app.json:

  [
    "@youssefhenna/expo-mapbox-navigation",
    {
      "accessToken": "****"
    }
  ],
  [
    "@rnmapbox/maps",
    {
      "RNMapboxMapsDownloadToken": "****",
      "RNMapboxMapsVersion": "11.3.0"
    }
  ]

  After I added these, This issue resolved. 

  Thank you for your support.
