Hello Zurbuchen, Simon,
I couldn’t find any outstanding issues reported internally. As a next step, you can try troubleshooting specific to Win32 app deployment and device enrollment:
Troubleshoot device enrollment in Intune - Intune | Microsoft Learn
If you have already gone through these or they don't resolve the issue, please reach out to support from here: Get support in the Microsoft Intune admin center | Microsoft Learn
Hope this helps!
