pmOS has a firewall (using nftables) enabled by default. IIRC firewalld can manage nftables, have you tried this instead of ufw?

Now ufw is working in v24.12. The only problem I've got is that I had to enable it in terminal 'cause there was some error when I tried to enable it in the Plasma Desktop settings.

firewalld still requires systemd );
