I've now triaged and fixed this issue. It was a problem in Go's
x/sys/windows library, which I've fixed upstream here:
https://go-review.googlesource.com/c/sys/+/270897

This should hopefully land soon, and I'll likely cut another release
to address this. I don't like taking down people's tunnels like this.

Thanks a lot for these logs and reports. I believe both of the issues
in this email thread are resolved.
