Getting Out of Memory Exception when loading in images

I get a system out of memory error after calling Image.FromFile in GetTarget(). How should I fix this?

        public ImageManager()
        {
            _tiles = new List<Bitmap>();
            GetTarget();
            LoadAll();
        }

        private void GetTarget()
        {
            _target = (Bitmap)Image.FromFile(@"C:\Users\timo2\OneDrive\Desktop\The Grind\Personal Projects\PhotoMosaic\PhotoMosaicGenerator\downloaded_images\image_20.jpg");
        }

        public ImageManager()
        {
            _tiles = new List<Bitmap>();
            GetTarget();
            LoadAll();
        }

        private void GetTarget()
        {
            _target = (Bitmap)Image.FromFile(@"C:\Users\timo2\OneDrive\Desktop\The Grind\Personal Projects\PhotoMosaic\PhotoMosaicGenerator\downloaded_images\image_20.jpg");
        }

Issue with DbContext reading in DB Tables

I am trying to use DbContext and the optionsBuilder to connect to my database and obtain a table called "Card". I am doing the following command in

OnConfiguring

OnConfiguring

optionsBuilder.UseSqlite($"Data Source=mtg.db");

optionsBuilder.UseSqlite($"Data Source=mtg.db");

and also have the following object instantiated in the same class:

public DbSet<Card> Card { get; set; }

public DbSet<Card> Card { get; set; }

Then, in my main method I run the following lines:

            var context = new MtgContext();
            var dbCards = context.Card.ToList();
            Console.WriteLine(dbCards);

            var context = new MtgContext();
            var dbCards = context.Card.ToList();
            Console.WriteLine(dbCards);

I get an error that "Card" is not a known table even though I have a Card table in the database. What am I doing wrong?
