Same thing here. Was working pretty well until the 40th Anniversary update. Now I’m getting CTD’s at the very first loader splash screen (before checking for updates). Odd thing is that one in every ten attempts it will load perfectly fine and then i can fly for hours without a problem. Very odd and annoying as hell.
Tried all the usual stuff like making sure everything’s up to date, SFC, DISM cleanup, cache clearing, complete reinstall etc. Nothing make as a difference.
