Failed to load message bundle in debug function

[slion-L]

i use the source code to generate the vsix file.
open a python file and first time click "Run and Debug"
it should shows

but it shows

if i press "F5", everything is ok.

Steps to reproduce:
git clone https://github.com/microsoft/vscode-python
cd vscode-python
npm ci
pip install black
npx gulp installPythonLibs
npm run package
install the vsix
open a python file
click "Run and Debug"
the quick pick window shows many "Failed to load message bundle. See console for details"

how to fix it?

Please see https://github.com/microsoft/vscode-python/wiki/Coding#building on how to build the extension. It looks like you didn't disable translations.
