ComfyUI not working

Hello,
I encounters following error (see attachment, ComfyUI is instaled in folder D:\Programy)., when I want to start ConfyUI.
[Error.txt](https://github.com/comfyanonymous/ComfyUI/files/14152718/Error.txt)
After instalation ConfyUI worked OK. But when I installed WAS node suite https://github.com/WASasquatch/was-node-suite-comfyui ConfyUI is not working any more with above error. I isntaled ConfyUI by methode described in https://stable-diffusion-art.com/how-to-install-comfyui/ in Win 10 Pro.
I tried to reinstall ComfyUI. This means to delete folder ComfyUI_windows_portable and againt install it withou instaling WAS node suite. This doesn't helps - ComfyUI still not working. I asked in WAS-NS Github and author answered me "This is a problem with a YAML file loading. WAS-NS doesn't use any YAML that I am aware of. I use JSON."

Does anybody have idea how to fix it and make ConfyUI working again with isntalled WAS-NS, please? I'm not familiar with Python etc. I tried to google this error. But I donn't have idea what to do in my case.

Thanks.
