Sure, you can find a generated version here: unreal_python_4.21.zip - Google Drive
It is worth noting though that it’s only broken when not generating API docs, so you can still run the doc gen commandlet yourself and you’ll get a stub file that’s correct for your project (you can stop it once you see the “…generated: Bla/Bla/Intermediate/PythonStub/unreal.py” line).
