Added '${workspaceHash}'

[Zingam]

Added another variable which is available in VS2019 too: https://docs.microsoft.com/en-us/cpp/build/cmakesettings-reference?view=vs-2019

${workspaceHash} – hash of workspace location; useful for creating a unique identifier

I don't know anything about that error either and indeed it doesn't look like being caused by your changes. I just queued a rerun, maybe it will pass. We'll investigate this error after the holidays, especially if we find that it gets triggered with other PRs.
