IntelliSense Errors on Visual Studio 2022.

Question

I have just started using visual studio 2022 for creating my first cross platform application. I installed an external library wxWidgets and started coding. The code return no errors on my code and when I select build only on Visual Studio terminal it returns no errors but on IntelliSense error it returns over 200 errors of c++ files.(When I created my project I opened an C++ project as wxWidgets is a C++ library.) At first I thought these errors won't be a problem as I didn't use the at all. Now when I run my project it returns these errors:

I have tried reinstalling my Visual Studio 2022 and repaired it I even installed the latest window SDK. I also thought maybe the cause of the problem my be my window so I updated my window. I have also tried enabling my IntelliSense and it still returns these errors. So that when I deleted the .vc folder and it still didn't help.

So I'm not sure what the problem here, so can anyone please help me. Thanks in Advance!!
