fix double python process

[vangeest]

The GUI is not always in line with the code
It look like starting the game with the arrow sometimes does not kill old processes
fix: remove errow in config, stat with python main.my

[vangeest]

Did some improvement in config by removing a task in the 25/26 release.

1. See if it is gone in classes of 25/26.
2. If not, another option would be to try if removing python extension helps.
3. Of not, another option would be to use start.sh script that kills all python processes before starting a new (don't know if this is what we want)
