Fatal Exception when loading multiple image files on Android from persistent data path

I'm having trouble to solve a Fatal Exception that is occurring when trying to load multiple .png files from my android persistent data path using Unity Web Request.

The coroutine that does the image loading is this:

 IEnumerator DoLoadSpriteFromLocal<T>(string p_loadPath, int p_loadID, T p_object, Action<bool, string, int, T, Sprite> p_callback)
     {
         string __loadPath = p_loadPath;
 #if UNITY_ANDROID
         __loadPath = $"file://{__loadPath}";
 #endif
 
         UnityWebRequest __uwr = UnityWebRequestTexture.GetTexture(__loadPath);
         var __operation = __uwr.SendWebRequest();
         
         float __timer = 0;
         while(!__operation.isDone)
         {
             yield return null;
             __timer += Time.deltaTime;
             if (__timer >= _timeoutTime)
             {
                 break;
             }
         }
 
         if (__operation.isDone)
         {
             if (__uwr.isHttpError || __uwr.isNetworkError) 
             { 
                 p_callback(false, $"Load sprite failed. \nLoad sprite path: {__loadPath} \nLoad sprite error: \n{__uwr.error}", p_loadID, p_object, null);
             } 
             else 
             {
                 Texture2D __texture = DownloadHandlerTexture.GetContent(__uwr);
                 Sprite __sprite = Sprite.Create(__texture, new Rect(0, 0, __texture.width, __texture.height), new Vector2(0.5f, 0.5f));
                 p_callback(true, $"Load sprite success. \nLoad sprite path: {__loadPath}", p_loadID, p_object, __sprite);
             }
         }
         else
         {
             p_callback(false, $"Load sprite timeout. \nLoad sprite path: {__loadPath}", p_loadID, p_object, null);
         }
     }

To load the images I start one of this coroutine for each one of the image files that I want to load. Then, after some loading the Android closes the game and point out a Fatal Exception with the following message:

There does not seem to be a pattern to when the Android will show this exception since the point at which he stops the game can vary (some times the game will run without any problems, but in the majority of times it will occur the exception).

I tried to use File.ReadAllBytes but the same exception appears.

If someone have a hint to where is the problem in my game would be of a great help!
