Crash with AttributeError: 'tuple' object has no attribute 'split' when trying to convert to onnx

Hi guys, I hope someone can help. installed the large all-in-one windows repo. When I try to convert pth to onnx the app traces back.
go_web.bat is starting well. When in WebGui on export onnx tab.
.
My Input (example):

RVC Model Path:
F:\pth\Shadowheart_250E.pth
Onnx Export Path:
F:\pth\Shadowheart_250E..onnx

What happens:

Running on local URL:  http://0.0.0.0:7897

AttributeError: 'tuple' object has no attribute 'split'

Whelp please?

Start with infer-web.py and infer/modules/onnx/export.py, then trace the failing export through infer/lib/infer_pack/models_onnx.py and infer/lib/infer_pack/modules.py. Reproduce the ONNX export with the paths in the report and determine why torch.onnx.export reaches torch.split with a tuple; done means the export completes without this AttributeError.
