Need help with visual studio for Unreal Enginer 5.3

UE5.3 requires a specific MSVC version, if you have a recent one, it might fail like the errors you are receiving.

For only 5.3 to work, you need MSVC 17.6 from Visual Studio Installer:

If that still doesnt work (double check in the output log which msvc version it using)
Do this manual workaround (set the proper msvc ver for 5.3)
