VS Code gulp scss save error, why?

Question

Sass

The question is this:
there is vs code ( deleted all plugins ) with a running gallop.
scss is open and gallp is tracking the change in the scss file.
All imports are correct!
But on every first save, galp throws an error, even on an empty file.
BUT , on the second save, the import works and the error disappears.
In other environments everything is fine and works.
What settings should be set for vs cod?
The screenshots show that an empty file with an error is saved, and then it is resaved without an error.
