Looks like the python-gi module is missing, you could try manually installing it.

Code:

sudo apt-get install python-gi

here says it's already the new version

sudo apt-get install python-gi

python-gi is already the newest version (3.26.1-2).

A post on Linux Mint forums :

suggests the following:

Code:

sudo apt-get install --reinstall gufw python3-gi

No issue here with the latest updates.

In the synaptic package manager: select installed packages: look for the package for the firewall : their is an option when you right click mouse - Re-install package..apply... Restart ...please.

You can open the editable xml page for your firewall with the following command: sudo ufw status verbose

You can change settings with the CLI. Make sure the defaults are deny (incoming) allow (outgoing) first, then you can allow or disallow ports.
