Unity Android Playform Build 'UnauthorizedAccessException' cant read file path is denied

[ohm0106]

Description of the bug

I have been using the native gallery 1.7.1 in Unity version 2018.4.36f1

I'm seeing the same bug as the title.
I tracked the issue and found that the bug started when I moved up to target version 12, and the bug log looks like this

The issue seems to be coming from that logic..

public static string GetAndroidInternalFilesDir()
{
    string[] potentialDirectories = new string[]
    {
        "/mnt/sdcard",
        "/storage/emulated/0",
        "/storage/sdcard0",
        "/storage/sdcard1",
        "/storage",
        "/sdcard",
    };

    if (Application.platform == RuntimePlatform.Android)
    {
        for (int i = 0; i < potentialDirectories.Length; i++)
        {
            if (Directory.Exists(potentialDirectories[i]))
            {
                return potentialDirectories[i];
            }
        }
    }

    return Application.persistentDataPath;
}

May I see the sections of your code that threw the exception? Particularly uGIF.CaptureToGIF function. Also I'm unaware of the GetAndroidInternalFilesDir function you've pasted above. Could you give more context on it?
