Closing sxiv in openbox crash

[Ladas552]

When using kunst from cli everything is fine, and I can even put command in Openbox rc.xml :

  <action name="Execute">
    <command>kunst --silent --music_dir ~/Music/ --size "240x135"</command>
  </action>
</keybind>

But if I close instance of sxiv that was opened openbox way it will crash a lot of programs such as:

• Network manager
• Firefox
• ClipIt
• etc
  except from terminals, tint2, mpv.
  I can't really show error log or output of kunst because if was summoned via hotkey
