Could you provide a replicator or instructions you are following?

Found no problem in Ubuntu 22.04: https://asciinema.org/a/ys5nUub96n24RuLUrQ0c0XRLr

@pablogs9 Thank you for your quick reply. I think I found the problem! Before I installed DDS-Agent, I had already installed Pytorch, NVIDIA GPU driver, etc., for deep learning. They make a conflict with DDS-Agent, maybe. I tried to reinstall Ubuntu, then install DDS-Agent. Now it is OKay!
