Environment

Steps to reproduce

colcon build --packages-up-to ardupilot_gz_bringup
. install/setup.bash
ros2 launch ardupilot_gz_bringup iris_runway.launch.py

Logs

[rviz2-8] /opt/ros/humble/lib/rviz2/rviz2: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE

Now, this is a likely a direct problem with rviz

This is not a problem of ardupilot_gz, it's caused by environment variables that VSCode sets breaking rviz: https://github.com/ros2/ros2/issues/1406

rfriedman@dev-rfriedman01:~/Dev/ardu_ws$ echo $GTK_PATH

The proposed solution below worked.

unset GTK_PATH

Since it's resolved by the other issue, I'm closing this.
