[fmauch]

Thank you for reaching out! The important line from your log output seems to be

[ur_ros2_control_node-1] [FATAL] [1720011769.120030745] [URPositionHardwareInterface]: Variable 'speed_slider_mask' is currently controlled by another RTDE client. The input recipe can't be used as configured

This looks like there might be a field bus active. In the ROS1 driver we have a sticky issue about that: UniversalRobots/Universal_Robots_ROS_Driver#204

The solution would be the same for ROS 2.

Since a solution has been proposed and the issue is quite old, I will close it.
Feel free to re-open, if still relevant.
