local untracked file is gone after git pull

 Git version:

PortableGit-2.28.0-64-bit.7z

Case:

Did a Git Stash in Visual Studio Code, before commit i did git  pull, then my changes and new files all gone.

Read article saying that git stash won't "add" new files(untracked)

But luckily still able get back all files(changes + new/untracked files) by git stash pop.
