VSCode debug/launch ROS2 node, preLaunchTask does not source the environment

edit

Hi

I like to use VSCode to debug my ROS2 project. But It looks like that the preLaunchTask is not working and ROS2 is not sourced. If I run my launch configuration I am getting the following errors on the Terminal and DEBUG CONSOLE. If I start vscode from an already source bash everything works, but I like to get it working without this workaround.

Terminal

/home/max/projects/car/ros2/dev_ws/install/cpp_pubsub/lib/cpp_pubsub/talker: error while loading shared libraries: librclcpp.so: cannot open shared object file: No such file or directory

The following tasks.json and launch.json shows my configuration. Can some give me a hint?
