Unity crashes trying to get pixels and using Debug.Log

The one that is doing the crases is the one "UnityEngine.Debug.Log(R)" line in the code, if it is deleted it won't crash, but I'll have no idea how to test if it works. This also happens if I made the list variable(InputLayer) public to the inspector. In short, Unity will crash if I try to view the list variable through anything.

Code:

 void Awake()
     {
         CurrentVidFrame = new Texture2D(608, 1080, TextureFormat.ARGB32, false);
 
         VideoPlayer.sendFrameReadyEvents = true;
         VideoPlayer.frameReady += OnNewFrame;
         VideoPlayer.Play();
     }
 
 
     //this is gonna work as the inputs
     void OnNewFrame(VideoPlayer source, long frameIdx)
     {
         RenderTexture.active = (RenderTexture)source.texture;
         Graphics.CopyTexture((RenderTexture)source.texture, CurrentVidFrame);
 
         //UnityEngine.Debug.Log(CurrentVidFrame); 
 
         // clear it every frame
         InputLayer.Clear();
 
         //getting each pixel (heavy as hell)
         for (int i = 0; i <(720 * 1280) - 1; i++)
         {
 
             float Col = i / 720;
             int columnOfFrame;
             columnOfFrame = (int)Math.Floor(Col); // rounds down to get the column number of pixels

             int row = i - (720 * columnOfFrame); // get the row number of the pixels

             // get the pixel color from the calculated numbers
             Color pixColor = CurrentVidFrame.GetPixel(row, columnOfFrame); 
             float R = pixColor.r * 255; // to get a value from 0 - 1
             InputLayer.Add(R); // add it to the list
 
             UnityEngine.Debug.Log(R); // and then this shitty line freezes unity
 
         }
     }

Please feel free to ask questions, I am quite stuck.
