SSH enable - Failed to start ssh.service

Just installed the new image , Volumio-4.119-2026-03-24-pi , on a raspberry Pi4 .
I cannot enable SSH from http://volumio.local/dev/ as it throws the error :

Unable to load host key: /etc/ssh/ssh_host_rsa_key
Unable to load host key: /etc/ssh/ssh_host_dsa_key
Unable to load host key: /etc/ssh/ssh_host_ecdsa_key
sshd: no hostkeys available – exiting.
ssh.service: Control process exited, code=exited, status=1/FAILURE
ssh.service: Failed with result ‘exit-code’.
Failed to start ssh.service - OpenBSD Secure Shell server.
