Just tested from Nemo:

Nemo cannot see Kubuntu 22.04 machine.

Could not display "smb://mach2/share

Error: Failed to mount Windows share: Connection refused

If it's broken from Nemo too, the issue is likely with the samba library itself. I would recommend that you report this to either the Kubuntu folks, or the Samba folks directly.
