The failed check is not caused by these changes, it's some kind of cmake failure.

Thanks so much! And yeah, this looks related to github updated windows-latest so that it used VS2022

More specifically that the cache for the old windows-latest is reused for the new version, since the cache key is based on runner.os which is just "Windows". Surprisingly there doesn't seem to be a way to get a more specific OS-version string:

Only workaround seems to be to specify the OS versions explicitly in the matrix: which isn't the worst thing, just something we'd need to occasionally remember to update
