Please uninstall completely firewalld on your system

sudo apt-get remove --purge firewalld

then follow below instruction to install it :

sudo apt update
sudo apt install firewalld
sudo systemctl enable firewalld
sudo systemctl start firewalld
sudo firewall-cmd --state ## to check the status 

sudo systemct status firewalld

I rename the ticket to align with the context
