Extension throwing TypeError: Cannot read properties of undefined (reading 'toString')

[kycutler]

We are seeing errors from recent versions of this extension causing our CI to fail. The error is:

Uncaught TypeError: Cannot read properties of undefined (reading 'toString')
at <...>\extensions\ms-python.debugpy-2025.6.0-win32-x64\dist\extension.js:2:849866
at FSReqCallback.readFileAfterClose [as oncomplete] (node:internal/fs/read/context:52:12)

Tracking down the line/column number shows it is coming from within src/extension/noConfigDebugInit.ts.

I have a PR to fix -- will open shortly.
