Last few insider builds (not necessarily because of it) Most of items in Start menu's just don't do anything. Command prompt/, Disk management, Device manager, Task manager etc. Other shortcuts for them work, each one when started from anywhere else works. I made links for them in various places including in desktop right click menu and on taskbar and all work from there.
I must have screwed up somewhere a while ago, all that works on my other computer that went thru same builds.
