ObstacleAssault, VS Code can't open sal.h

[DanM]

To be clear, I’m not telling you to install that. You said everything is working with Visual Studio and you’re using Unreal 5.3 which has problems with the current latest version of MSVC that is installed with it 14.39, you’d be unable to build. So you must already have a different version installed that you’re using.

See:

Compiling issue. UE5.3

Edit 2: There is a bug in MSVC 14.39 that effects UE 5.0 and 5.3. 5.4 also bans that version of MSVC. In 5.0 that would appear as errors regarding TStringConversion, use the instructions below to downgrade to 14.38. In 5.3, errors regarding FHazardPointerCollection, with the latest version of 14.39 this no longer causes that error on my end so updating Visual Studio should fix this. In 5.4 Epic has banned use of 14.39 so you would need to downgrade. You should only need to follow the steps be…

I’m saying to change the compiler path in that JSON file to be the version that Unreal is using to compile the code. As it currently using the path to the buggy 14.39 compiler.
