Python debugging will not start on Windows 10 + Sublime build 4126

[scrovy]

I've installed the latest version v0.6.7 of the debugger, the python adapter and copy pasted the example under C:\[sublime install dir]\Data\Packages\Debugger\examples\python to a local directory called example_python.

With the default configuration python.sublime-project which comes with the example:

{
    "folders": [
        {
            "path": ".",
        },
    ],
    "debugger_configurations": [
        {
            "name": "Python",
            "type": "python",
            "request": "launch",
            "program": "${project_path}/main.py",
        },
    ],
}

the debugger will not start and the command log (CTRL+`) is as follows:

Changed the font setting "font_face": "Monospace" to "font_face": "Consolas" in the file debugger.sublime-settings inside the package, and the error changes to

Debugger: error: Closing Debugger Console View it is not attached to a console

Tried all options "console": "integratedTerminal", "internalConsole" and "externalTerminal" and all give the same error, except that now the error message Debugger: error: Closing Debugger Console View it is not attached to a console disappears (but still CancelledError occurs). (Note: the terminus package is installed, hence externalTerminal should also work?) Also tried a more extensive configuration file

{
    "folders": [
        {
            "path": "C:\\explicit\\path\\to\\example_python",
        },
    ],
    "debugger_configurations": [
        {
            "name": "Python",
            "type": "python",
            "request": "launch",
            "console": "integratedTerminal",
            "program": "C:\\explicit\\path\\to\\example_python\\main.py",
            "justMyCode": true,
            "RedirectOutput": true,
            "debugOptions" : {
                "RedirectOutput": true,
            },
            "python": "C:\\[pythonpath]\\Python310\\python.exe",
            "cwd": "C:\\explicit\\path\\to\\example_python",
            "stopOnEntry": true,
        },
    ],
}

but it didn't help. Tried to fiddle with the open_at_startup option of debugger.sublime-settings, but with no avail. Any ideas?

What does running Debugger: Show Protocol reveal?

[scrovy]

Apparently the debugger is having trouble finding python:

⟸ process/starting :: ['python3', 'C:\\[...]\\Sublime Text Build 3211 x64\\Data\\Packages\\Debugger/data/adapters/python/extension/pythonFiles/lib/python/debugpy/adapter']
⟸ process/started ::
⟸ request/initialize(1) :: {'clientID': 'sublime', 'clientName': 'Sublime Text', 'adapterID': 'python', 'pathFormat': 'path', 'linesStartAt1': True, 'columnsStartAt1': True, 'supportsVariableType': True, 'supportsVariablePaging': False, 'supportsRunInTerminalRequest': True, 'supportsMemoryReferences': True, 'locale': 'en-us'}
⟸ process/stderr :: P
⟸ process/stderr :: ython was not found; run without arguments to install from the Microsoft Store
⟸ process/stderr :: ,
⟸ process/stderr ::  or disable this shortcut from Settings > Manage App 
⟸ process/stderr :: E
⟸ process/stderr :: xecution Aliases.

⟸ process/stopped :: 

But I do have the python executable in the configuration file:

            "python": "C:\\[...]\\Programs\\Python\\Python310\\python.exe",

All the mentioned paths/executables exist, I've double checked it.

The adapter configuration looks at pythonPath not python. I see python in the json schema though so it probably was changed to use python instead of pythonPath on Microsoft side.

That was it, thanks! Some config elements were wrong so hereby the (most simple) configuration that made it work:

{
        "folders": [
                {
                        "path": ".",
                },
        ],
        "debugger_configurations": [
                {
                        "name": "Python",
                        "type": "python",
                        "request": "launch",
                        "program": "${project_path}/main.py",
                        "pythonPath": "C:\\path\\to\\Python310\\python.exe"
                },
        ],
}

Also you might need "console": "internalConsole", if it still doesn't work.
