I’ve used this cursor theme for some time https://www.gnome-look.org/p/999986. The issue is that I now use the default Adwaita cursor theme, however the following icon still remains and I can’t get rid of it:

I tried to execute:
sudo touch /usr/share/icons/Adwaita
sudo gtk-update-icon-cache -f /usr/share/icons/Adwaita
