The VS code app does not see the ofstream class from the fstream library. What to do?

Question

Visual Studio Code

I connect as usual #include <fstream>. Then I try to create an object of the ofstream class, but Vs code does not see this class. I googled and didn't find similar problems. Installed the extension for c++, created new projects several times. Does not help.

Point to the sky... But do you access std::ofstreamor use using namespace std;?
