A clean vcpkg clone works fine, it'd be nice if vcpkg could recover from this failure itself though.

delete file
...\vcpkg\downloads\tools\msys2\initialized-msys2_64.stamp or initialized-msys2_32.stamp

after this, MSYS2 will be completely reinstalled

@OlafvdSpek, do you try the step that Voskrese provided? you can remove ./downloads/tools/msys2 folder and try to build it again.

[OlafvdSpek]

I nuked the entire vcpkg directory and started from scratch..

[PhoebeHui]

That's fine, this issue has been fixed.

[OlafvdSpek]

But existing instances don't recover automatically..

[PhoebeHui]

Sorry @OlafvdSpek, I will try to improve this.
