HR Module in ERPNext V16 issue

Dear, I have a problem since I updated to V16, the Frappe HR is nor working well, and the people icon is not showing as indicated in below snapshot and whenever i click it i get a message: Icon is not correctly configured please check the workspace sidebar to it.

Any Help…

Any help please

I ran into something similar after jumping to v16, and it turned out the HR workspace JSON didn’t update cleanly. I fixed it by going to Workspace List, opening the HR one, and hitting Reset to Defaults. If that doesn’t do the trick, try clearing cache and running bench migrate. Sometimes the update leaves old configs stuck halfway and a reset kicks things back into place.
