Install docker on RHEL 8.8. Service does not start because of error : "Failed to initialize nft: Protocol not supported"

Question

We're trying to install docker on RHEL 8.8 :

• containerd.io-1.6.28-3.2.el8.x86_64.rpm

• docker-ce-25.0.5-1.el8.x86_64.rpm

• docker-ce-rootless-extras-25.0.5-1.el8.x86_64.rpm

• docker-ce-cli-25.0.5-1.el8.x86_64.rpm

• docker-compose-plugin-2.25.0-1.el8.x86_64.rpm

When starting service with "systemctl start docker.service", we get the error :

-- Unit docker.service has begun starting up.

We rebooted the machine, we tried to reinstall nftables and iptables, and changing versions.
