I have the same problem. Did you find a solution?
uwp app got hanged for 4-5 sec and it is getting crashed sometime
When I'm running my UWP app I am consistently seeing the following output in the output window::
onecore\com\combase\dcomrem\marshal.cxx(1111)\combase.dll!76DC4858: (caller: 76D4A70C) ReturnHr(10) tid(9fb4) 80004002 No such interface supported
