Can't open lesson group of 3DEXPERIENCE EDU learning module

It seems I cant open lesson group "Extend your Knowledge to the PLM World" in "Explore the 3DEXPERIENCE SOLIDWORKS Student Role (2021)" Learning Module.
I can open all other lesson group, but not this one even after waiting 30 minutes. Can someone verify or give me the solution to open it?
Thank you
