We can't give advice with so little information. You need to:

Show the code which generates these errors. Copy & paste, don't retype it.

Copy & paste the error messages from the Output or Error List window.

Tell us how you created the file/project you are trying to build.

Tell us what packages you chose to install when you installed VS 2019.

If Visual C++ lost the C++ headers, then did you override the include paths?
This is the kind of result I would expect if you changed the Include Directories in the VC++ Directories and didn't inherit the old paths.

@ALI RAZA ,I suggest you could try to go to Project and hit Rescan Solution to recreate it.
