Fails to install successfully built package for Windows x86

Maybe this is not maturin-action's fault, I just don't know where to ask.

I created a github workflow using maturin generate-ci --pytest github > .github/workflows/CI.yml. It builds a python3-rust hybrid package using maturin 1.4.0, pyo3 0.20.0 (github.com/mRcSchwering/magic-soup). All OSs and architectures are built, and for Linux and MacOS the pytest step runs green as well (CI.yml below).

Just for Windows x86 the pytest step doesn't run. Looking into the logs I can see that during the package installation in the test environment it seems to ignore one of the package dependencies.

My package has 2 dependencies: numpy and torch. During pip install magicsoup --find-links dist --force-reinstall it correctly starts to collect numpy. But then it doesn't collect torch and instead continues to install my package from the cached wheel:

Afterwards, when tests are started, it fails at import torch because it didn't install it. This is strange because this behaviour doesn't exist in other OSs or architectures. E.g. here is the same step but from MacOS x86_64:

As you can see it correctly installs numpy and torch. I only have a Linux so I can't really reproduce this problem locally. I only see it in the github pipeline.
