launch.json problems: "Configured debug type 'python' is installed but not supported in this environment."

[dmorse76]

Issue Type: Bug

For some reason, my .vscode/launch.json for my Python project has started reporting problems for each configuration, even the default:

    {
        "name": "Python: Current File",
        "type": "python",
        "request": "launch",
        "program": "${file}",
        "console": "integratedTerminal"
    },

The problem is always "Configured debug type 'python' is installed but not supported in this environment.", yet these debug configurations work just fine (as they always have).

Closing in favour of #136712 even though that one is later, because it was created from Python extension issue microsoft/vscode-python#17952
