Environment data

• PTVSD version: ms-python.python-2019.10.44104
• OS and version: Mac OS X, 10.15
• Python version (& distribution if applicable, e.g. Anaconda): 3.7.4
• Using VS Code or Visual Studio: VS Code

Actual behavior

When I try to launch one of my launch configurations, I get:

/Users/willy/src/doorstead/api/.venv/bin/python: can't open file '/Users/willy/.vscode/extensions/ms-python.python-2019.10.44104/pythonFiles/ptvsd_launcher.py': [Errno 2] No such file or directory

It looks like the file ptvsd_launcher.py doesn't exist locally for me in the directory for the ms-python extension?

Expected behavior

If I downgrade to ms-python.python-2019.10.41019, then I can launch the target as expected (because ptvsd_launcher.py exists as expected):

Steps to reproduce:

1. Install the latest Python extension for VS Code (ms-python.python-2019.10.44104), which looks like it was released ~an hour ago
2. Go to Debug and try to launch one of the configurations

@willywu Please could you uninstall the extension, then delete the folder ms-python.python-2019.10.41019 Next reload VS Code and reinstall the latest version of the extension.
