When you remove an item (or add one) to a list it messes up the Selected values. You can't rely on them being valid anymore. What you need to do is copy the selected values somewhere else then use that new copy to remove the items.

Try using SelecredIndices collection:

public Form1()
        {
            InitializeComponent();
            
            //my test population:
            char[] array = "abcdef".ToCharArray();
            for (int i = 0; i < array.Length; i++)
                listBox1.Items.Add(array[i]);
            listBox1.SelectionMode = SelectionMode.MultiExtended;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            while (listBox1.SelectedIndices.Count > 0)
                listBox1.Items.RemoveAt(listBox1.SelectedIndices[0]);
        }

SelectedIndices makes it worse, as each time you remove an item the Indices change.

This was tested and works:

private void button1_Click(object sender, EventArgs e)
        {
            while (listBox1.SelectedItems.Count > 0)
            {
                listBox1.Items.Remove(listBox1.SelectedItem);
            }
        }
