FaceFusion fails to validate downloaded models on Windows 11 25H2 (WinError 32)

Environment

• FaceFusion: 3.6.1 and 3.7.1
• Pinokio: 8.0.0
• Windows 11 Pro Insider Preview 25H2 (Build 26200.8655)
• GPU: NVIDIA GeForce RTX 5050
• NVIDIA driver: Latest
• Python: 3.12
• ONNX Runtime: CUDA

Problem

FaceFusion downloads the model successfully, but immediately fails during the validation step.

Example:

[FACEFUSION.DOWNLOAD] validating source for nsfw_3 failed

Traceback:

PermissionError: [WinError 32] The process cannot access the file because it is being used by another process

The error happens with different models:

• fairface.onnx
• yoloface_8n.onnx
• nsfw_3.onnx
• 2dfan4.onnx

The file downloads correctly, validation fails, then FaceFusion tries to delete the file and raises WinError 32.

What I already tried

• Clean reinstall of Pinokio
• Clean reinstall of FaceFusion
• Manual GitHub installation (without Pinokio)
• FaceFusion 3.6.1
• FaceFusion 3.7.1
• Deleted Pinokio's openssl-3.6.3-hf411b9b_0 package
• Updated NVIDIA drivers
• Disabled Windows Defender
• Deleted all downloaded model files
• Verified internet connection (HuggingFace returns HTTP 200)
• Python 3.12 environment

The exact same error happens every time.

Additional information

The files are actually downloaded successfully.
The failure occurs only during validation, when FaceFusion attempts to remove the "invalid" model file.

Could this be related to Windows 11 Insider 25H2 or the download validation logic?
