Description

This is a new one today:

From a recent workflow run: https://github.com/Ouranosinc/xscen/actions/runs/25866938467/job/76012677697

At first, I figured it might be due to the changes to windows-latest (20252026), but even after forcing 2025, I am getting the exact same errors. No issues before this morning.

This started occurring with setup-micromamba v2.0.7, but upgrading to v3.0.0 has not had any positive impact (beyond muting node.js warnings).
