Error with Bazel 6 on Windows

CI fails on Windows when using Bazel 6.0.0:

Do you know when this started happening? Was it a change in this repo that caused it or some external change in bazel?

If there is no quick for this I think we should perhaps disable that test in CI since its blocking all other changes here.

I believe it started when 6.0.0 was released and picked up the CI pipeline.

#1151 includes a workaround (pinning the Windows build to 5.4.0). If you like I can extract that to a separate PR.

Actually that would be great yes!
