Dependencies not included in final zip package

Issue description

I have following in the serverless.yml

custom:
  pythonRequirements:
    dockerizePip: true
    usePipenv: true
    slim: true
    useDownloadCache: true
    useStaticCache: true

package:
  individually: false
  excludeDevDependencies: true
  patterns:
    - "!**"
    - "src/**"

This correctly includes both source code in src and generated dependencies from .serverless/requirements on CI that uses Ubuntu.

Locally on my Windows machine dependencies are not included in the final zip package even though they are generated.

Log output:

Packaging "X" for stage "test" (eu-north-1)

If I reinstall and restore serverless-python-requirements plugin

plugins:
  - serverless-python-requirements

I get final zip package with source code and the dependencies.

Is this some sort of regression that came with integrating the plugin to core framework or something in my setup is just wrong?

Context

serverless 4.31.2
pipenv 2026.0.3
Windows 11
