Per our discussion in slack - we may want to consider bumping the cache in one of these ways:

  • Adding a -v0- parameter that we can bump to invalidate the cache
  • Using matrix.os instead of runner.os for the cache here - that will use windows-2022 instead of windows for the cache key

Nice catch... It's surprising that this is necessary, but glad you found it.
