So in editor it shows as an error for every standard library module, but when I compile it, it works without a problem. The only annoying thing with this is that because of this the autocomplition doesn’t work.

Yesterday when I created the project everything was fine, but today after I opened it to continue working it gives me theese to message.

Tried using namespace, nothing.
