I have Object Desktop and Start 10 is installed, both latest versions. I think it has something to do with Start 10 because I can pin apps to Start 10, which I did, but not to the regular start menu. And yes its blank before any skin is loaded. My real concern is why the sfc scan finds corrupt files after an update was installed. I looked into the CBS log file but to make sense of it...meh. As for 1809 (September release)...1804 (April release) is just five months older. According to Mr. Pritchard. Anyway I solved the issue by pinning those apps to Start 10. MS's start menu my be glitchy but Start 10 works and that's all I care about.
