title: Trying to run plt.show() creates error message
body: <p>executing the command 'plt.show()' shows the following error message: 'Process finished with exit code -1073741819 (0xC0000005)'.</p>
  <p>I updated all my packages and after that, i always got the above-mentioned error message. Downgrading the matplotlib version to a lower one could not solve the issue. If I remove the command 'plt.show()', it'll work properly.</p>
  <p>Can anyone help me?</p>
  <p>Here is the examplary code that I try to run:</p>
  <pre><code>xpoints = np.array([1, 8])
  ypoints = np.array([3, 10])
  
  plt.plot(xpoints, ypoints)
  plt.show()
  </code></pre>
