One thing I'm noticing with your config is that you have the same ip assigned to both clients.

The entries you have in the config files under the [left] and [right] sections should refer to the target IP of the respective devices.

Okay I can reproduce this issue. There seem to have been changes in Hyprland.

Oh sorry is a mistake, in my copy paste.

Seems to be an issue with Hyprland introduced in 28a90d6055

I will see what I can do.
No need for the log anymore ;)
