Hi
The Zorin Appearance Window is smaller than other GTK4 themes and can't be resized.

Thanks for your great job

This also affects several other dialogues popping up, not only on ZorinOS. The Ubuntu software updater confirmation dialogue ("your software is up to date..") also gets shrinked and cannot be resized.
