I added the Windows CI with skipping those tests.

I'm experiencing the same issue now in 2025 on Windows. Doing a command with --track-memory fails exactly like the OP described. For brevity here's my output with some folder names stripped out for privacy

Other information:

• I'm running Python 3.12
• I'm using uv for environment management, and the commands I was using were as follows:
  • uv run pyperf command --track-memory --name "test sleep" sleep 2

I can confirm running the above command on Windows causes the error, while doing so on Mac or WSL succeeds.
