Collect Perforce Login - Pywin32 error in not compatible hosts

[antirotor]

Is there an existing issue for this?

• I have searched the existing issues and added correct labels.

Description

Current Behavior

Whenever https://github.com/ynput/ayon-perforce/blob/develop/client/ayon_perforce/plugins/publish/collect_perforce_login.py
runs, it needs pywin32 because AYON is accessing keyring and that in turn needs pywin32. It is binary dependency and currently it is shipped with the launcher. If host python differs from what we have in launcher (currently python 3.9), it crashes.

Note

This is specific for Windows.

Expected Behavior

We either need to provide working pywin32 to every supported hosts (but for that we would need to build it) or we need to delegate keyring access to AYON process - call subprocess from pyblish plugin to get the information.

Steps To Reproduce:

Run Maya 2025 (or any other host without python 3.9) along with the ayon-perforce. collect_perforce_login plugin will crash on publish.

Additional context:

Version

This happens on 84193f8

Note

Workaround is to limit the plugin to Unreal host right now so it won't break anything else until resolved
