Cannot execute c1xx.dll - build/compile issue with UE5.5

Top of the day to you all

I currently can’t build any ue5.5 c++ projects in visual studio (or rider) and get a D8027 error or ‘cannot execute c1xx.dll’

  • this effects VS and Rider and I don’t have this problem with ue5.4 c++ projects
  • I’ve even reinstalled VS to cleanup my tooling and its not fixing the issue…
  • I’ve tried adding to build.cs files bLegacyPublicIncludePaths = false;

There is not alot of info out there so any tips/thoughts would be greatly appreciated!

We have the same issues here, with any UE5 build above 5.5.

We’ve tried 5.5 and 5.6 now and are still getting these errors on compile.
We also use Rider and Visual C, but have tried without Rider, but still get the same error.

Any help to get around this and we’d be super grateful!
