I assume you are using Visual Studio as your build tool? The LLVM project set turns into a bunch of Visual Studio project files, and my experience has been that they do not always coordinate correctly. Often just running the build again will solve a problem like this. I’m not really familiar with the sanitizers so I don’t have any ideas about the specific error, if re-running the build doesn’t solve it.

I used to build llvm/clang on windows a lot, and never had any issues.

But I never built asan on windows, maybe asan just doesn't build on windows?
