catfish won't open on Debian 10

after installing when I tried to open catfish, nothing comes up. I am using Debian 10 Buster.

When I tried to open through terminal. It gives the following

(catfish:11171): Gtk-WARNING **: 20:59:07.726: ../../../../gtk/gtkwidget.c:8584: widget not within a GtkWindow
Traceback (most recent call last):

  File "/usr/lib/python3/dist-packages/catfish/__init__.py", line 76, in main
    window = CatfishWindow.CatfishWindow()
  File "/usr/lib/python3/dist-packages/catfish_lib/Window.py", line 169, in __new__

    (display_width, display_height) = self.get_display_size()

    m = s.get_monitor_at_window(s.get_active_window())
TypeError: Argument 1 does not allow None as a value

How can I resolve this issue ? please help
