Windows 10 Stock Menu Disappears, Start10 Works Fine

Hey all, running Start 10 v1.55.  My issue is Start 10 works flawlessly, however after a certain period of time, default Windows 10 Start Menu refuses to open.  I've tried recreating the pinned shortcut with no luck.  Oddly enough, if I keep the stock Windows 10 menu open, it'll work just fine, if I close it out, after a certain period of time it just seems to stop working.  Not sure if there is a service or dependency that isn't working properly but I've scanned for errors, reinstalled Start 10 with no luck.  Any help is appreciated, I don't use the Windows 10 default menu often, but having the functionality there for if and when I need it is handy.
