[llvm-dev] Ninja hangs when I try to build

[Paul C. Anagnostopoulos via llvm-dev]

I tried my first build after switching to origin main. I did the switch by renaming my master branch and then pointing it at origin main.

I just tried to build llvm-tblgen. It fails building RandomNumberGenerator.cpp.obj with "C1902: Program database manager mismatch; please check your installation" Then it hangs; Ctrl+C does nothing.

I killed the window and started it up again. This time I tried a full build. It hangs building DebugCounter.cpp.obj.

I'm running Visual Studio 2019 on Windows 7. Has anyone else seen this?
