This is a minimal github workflow script that reproduces the issue: ``` name: Build and test on: push: branches: - debug/qsharpwin env: IQSHARP_TELEMETRY_OPT_OUT: 1 jobs: windows: name: Build and test...

The error goes away if I update `pyzmq` with `pip install -U pyzmq` after installing `qsharp`. Unfortunately, this then falls foul of #376 and we get unpredictable hangs.
