<div class="markdown_content"><p>Hi! I know this issue is too old but today I had the same problem and suddenly I couldn't open Codesys window. My solution after several attempts was just to open task administrator and when Codesys is running, right click in Codesys application and select "bring to front" option. Magic!</p></div>
