Passing --no-enable-webtransport-h3 works around the issue for now.

What version of cryptography do you have installed? (I presume this just exists only as a dependency that we don't pin, which seems bad?)

Like, what's d:\gecko\testing\web-platform\tests\_venv3\bin\pip3.exe freeze give?

41.0.5, it seems.
