'Array Dimensions exceeded supported range' on Save to jpg on very large file

I have a PSB files that are 57953 x 15039 pixels (and similiar sizes). I am trying to get a resized jpg image however I am getting error after Resize and then Save. Also receive error same error if I just run image.Flatten() without any resize or save. Seem like it can’t handle a something this size?
