Troubleshooting

Basically, if it doesn't work, you can look at the output or the error log, but I will note what seems to happen most often.

Featuring ROS2

cargo build --release --features ros2
cargo install --path ./openrr-apps

Please make sure that ROS2 is enabled before these commands.

GUI Troubleshooting

Please check openrr-gui README

If this does not resolve the issue

It may be a bug in OpenRR, so it would be helpful if you could open an Issue in the repository Issues.
