Debugging with the gazebo simulator closes immediately

I have opened the PX4-Autopilot code in VSCode. I am not using docker. Whenever I try debugging SITL (gazebo), it looks like everything is working, but nothing opens up and the debugger ends immediately.

> Executing task: make px4_sitl_default sitl_gazebo <

[0/3] Performing build step for 'sitl_gazebo'
ninja: no work to do.

> Executing task: killall px4 || true <

px4: no process found

> Executing task: rm -rfv /tmp/px4* <

removed '/tmp/px4_lock-0'

> Executing task: killall gzserver <

However, VSCode displays a message:

err

How do I get the debugger to work? For anyone interested, here’s the debug log.
