shows errors or corrected errors only after compilation

[eismeraldo]

Everything has worked perfectly so far. Suddenly, no more errors are displayed, neither when typing nor after saving. The error only appears after a compilation or disappears after a correction and subsequent compilation.
The property mentioned in the community looks like this on all four levels: "C_Cpp.errorSquiggles": "enabledIfIncludesResolve"
I had noticed that the extension C/C++ IntelliSense, debugging, and code browsing was updated about an hour previously. A version that was a month older did not fix the error.
Uninstalling and reinstalling VS Code did not fix the error either.
Does anyone have any idea what could be causing this?
Thank you very much for your help.
