  <p>When I'm opening bash.exe directly from C:\Program Files\Git\bin it works fine.<a href="https://i.stack.imgur.com/h8zFl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/h8zFl.png" alt="enter image description here"></a></p>
  
  <p>Also when I'm running this from cmd.exe it works. The problem is only when I'm trying to run it from git extension.<a href="https://i.stack.imgur.com/wylZn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wylZn.png" alt="enter image description here"></a></p>
  
  <p>What can it be?</p>
