4.23 is building successfully but crashing on start-up (VectorIntrinsics Failed)

I’ve just finished building UnrealEngine-4.23 from the release branch of the repo. Everything has built successfully, but whenever I try to fire up Unreal Engine and see the launcher, it cuts back to Visual Studio and gives me this error. Is anyone else having this issue or know how to resolve it?


Fatal error: [File:C:/UnrealEngine/Engine/Source/Runtime/Core/Private/Tests/Math/UnrealMathTest.cpp] [Line: 1525] 
VectorIntrinsics Failed.

This is a known issue in the latest compiler.

If you install an earlier version of the windows SDK (which has an earlier compiler without the regression), then you can build UE4 using the following BuildConfiguration.xml:

Put this in SOURCE\Engine\Saved\UnrealBuildTool\BuildConfiguration.xml.

I had the same issue and got crazy on this one. I built the engine twice and it still failed. Is there a way to solve it?

@wcl1993 yes, follow the instructions I posted or wait for Microsoft to fix the problem in the link I included (which I believe is going to be in VS 16.4).

Thank you for the fix drichardson, that worked perfectly! So glad to have a working build again. I didn’t need to include the WindowsSdkVersion for that one, as it was already using the one listed. I’ll keep a lookout for the 16.4 version of VS and hope that it resolves the issue for good.
