Jetbrains toolbox does not start on WSL2

You only have a black screen when you want to start the jetbrains-toolbox within WSL?

goto: ~/.local/share/JetBrains/Toolbox and edit the .settings.json to include:

    "internal": {
        "graphics_api": "Software"
    },

try starting again (maybe you have to kill -9 your previous toolbox start)
