// What I’m using
-Unreal 4.25
-macOS Big Sur
-Visual Studio
//What I expected to happen
Before upgrading to Big Sur, I was able to compile and run my Bull Cow Game.
I expected to hit compile and be able to run my application inside of Unreal.
// What happened
I get a compile error.
The project could not be compiled. Would you like to open it in Visual Studio Code?

Building BullCowGameEditor…
[Upgrade]
[Upgrade] Using backward-compatible build settings. The latest version of UE4 sets the following values by default, which may require code changes:
[Upgrade] bLegacyPublicIncludePaths = false => Omits subfolders from public include paths to reduce compiler command line length. (Previously: true).
[Upgrade] ShadowVariableWarningLevel = WarningLevel.Error => Treats shadowed variable warnings as errors. (Previously: WarningLevel.Warning).
[Upgrade] PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs => Set in build.cs files to enables IWYU-style PCH model. See https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html. (Previously: PCHUsageMode.UseSharedPCHs).
[Upgrade] Suppress this message by setting ‘DefaultBuildSettings = BuildSettingsVersion.V2;’ in BullCowGameEditor.Target.cs, and explicitly overriding settings that differ from the new defaults.
