All shadergraphs have "undeclared identifier 'BuildVertexDescriptionInputs'

Hi there,
all shadergraphs in my project have this error. Im on Windows 11 and Unity 2020.3.23.f1 - URP.
Graphic driver is up do date.
Is this a bug related to win11? Or can I do something about it :confused:
Any help is appreciated :slight_smile:
Thanks!

EDIT: When I build the same shader in a clean URP file, I dont get any errors. Any settings to change? Anything I can reset?

same issue, any help?
