Item group issue

Hi,

I have install ERPNEXT fresh:

ERPNext: v12.1.1 (version-12)

Frappe Framework: v12.0.11 (version-12)

When I try to add an Item group, I am getting this error. Can someone help me?
Item Group All Item Groups not found
The resource you are looking for is not available

Thanks,
Zia
