Unable to re-enter a iOS (Mini Ipad 2022) build with AR functions

Hey everybody,

I have the problem that I can enter and play my build on the Mini Ipad 2022, but I can’t re-enter it. I don’t have this if I disable my AR functions.

To be specific: I get stuck on the splash screen (without showing the icon) when I enter after close the app.

Why is this and how can I fix this?

Unity version: 2022.3.12f1
Xcode version: 15.2

Packages: Packages - Album on Imgur

I already tried to fix it with this, but sadly this makes it that leaving and entering without fully closing isn’t plossible anymore:

using UnityEngine;
using UnityEngine.XR.ARFoundation;

public class ARSessionManager : MonoBehaviour
{
    private ARSession arSession;

    void Awake()
    {
        arSession = FindObjectOfType<ARSession>();

        // Initialize the AR session
        if (arSession != null)
        {
            ResetARSession();
        }
    }

    void Start()
    {
        if (arSession != null)
        {
            Debug.Log("AR Session started.");
        }
    }

    // Reset ARKit when entering the scene (only call this when needed)
    private void ResetARSession()
    {
        if (arSession != null)
        {
            // Stop AR session
            arSession.enabled = false;

            // Clear AR session state (ARKit-specific reset)
            arSession.Reset();

            // Restart AR session
            arSession.enabled = true;
            Debug.Log("AR session has been reset.");
        }
    }

    // Handle when the app is paused or resumed
    private void OnApplicationPause(bool isPaused)
    {
        if (arSession != null)
        {
            if (isPaused)
            {
                // App is going to the background, disable AR session
                Debug.Log("App paused, stopping AR session.");
                arSession.enabled = false;
            }
            else
            {
                // App is returning from background, restart AR session with a delay
                Debug.Log("App resumed, restarting AR session.");
                StartCoroutine(RestartARSessionWithDelay(1.0f)); // Wait 1 second before restarting
            }
        }
    }

    // Handle when the app loses or gains focus
    private void OnApplicationFocus(bool hasFocus)
    {
        if (arSession != null)
        {
            if (!hasFocus)
            {
                // App loses focus, disable AR session
                Debug.Log("App lost focus, stopping AR session.");
                arSession.enabled = false;
            }
            else
            {
                // App gains focus, restart AR session with a delay
                Debug.Log("App gained focus, restarting AR session.");
                StartCoroutine(RestartARSessionWithDelay(1.0f)); // Add delay for smoother transitions
            }
        }
    }

    private IEnumerator RestartARSessionWithDelay(float delay)
    {
        yield return new WaitForSeconds(delay);  // Wait for a small delay to let ARKit stabilize

        if (arSession != null)
        {
            arSession.enabled = true;
            Debug.Log("AR session restarted after delay.");
        }
    }

    private void OnDestroy()
    {
        if (arSession != null)
        {
            arSession.Reset();
            Debug.Log("AR session cleaned up on destroy.");
        }
    }
}```

I also tried to fix it by deleting the temp files:

```using UnityEngine;
using System.IO;

public class TempFileCleaner : MonoBehaviour
{
    // Path to Unity's persistent data directory (used for storing temporary data)
    private string tempFolderPath;

    void Start()
    {
        // Initialize the temp folder path (change this if you store temp files elsewhere)
        tempFolderPath = Application.temporaryCachePath;

        // Delete temp files on app relaunch
        DeleteTemporaryFiles();
    }

    // Function to delete files in the temp folder
    void DeleteTemporaryFiles()
    {
        // Check if the folder exists
        if (Directory.Exists(tempFolderPath))
        {
            // Get all files in the directory
            string[] tempFiles = Directory.GetFiles(tempFolderPath);

            // Loop through all files and delete them
            foreach (string file in tempFiles)
            {
                try
                {
                    // Attempt to delete the file
                    File.Delete(file);
                    Debug.Log("Deleted temp file: " + file);
                }
                catch (IOException ex)
                {
                    Debug.LogError("Failed to delete temp file: " + file + "\n" + ex.Message);
                }
            }

            Debug.Log("All temporary files deleted.");
        }
        else
        {
            Debug.Log("Temp folder not found: " + tempFolderPath);
        }
    }
}```
