Why does Gulp in Visual Studio Code highlight a hyphen as an error in SCSS code?

Question

Sass

Greetings, please tell me why now Gulp in VSC began to highlight the HYPHEN in red as an error in the SCSS code? This was not the case before. I can't figure out what's wrong. In the console, too, EXPECTED displays all these lines as errors.
What's wrong, what's broken?

In the console for each line there is such an error
[{
"resource": "/d:/....../_contacts.scss",
"owner": "_generated_diagnostic_collection_name_#0",
"code": "css-rparentexpected",
"severity": 8,
"message": ") expected",
"source": "scss",
"startLineNumber": 5,
"startColumn": 41,
"endLineNumber": 5,
"
