Description
Testing #859
At step 1.1, the first time I ran a python program I ran into the following error. I did not see it again afterward, not sure what the problem was.
python-debug-test & 'C:\src\_test\python-debug-test\.venv\Scripts\python.exe' 'c:\Users\bevillal\.vscode-insiders\extensions\ms-python.debugpy-2025.15.2025110302-win32-x64\bundled\libs\debugpy\launcher' '53935' '--' 'C:\src\_test\python-debug-test\root_script.py'
