Same here… I have no idea how to fix it. Asobo Zendesk answer was a default answer that only told me to do all the stuff I already tried. I also reinstalled the sim 2 times and cleared every left folder on my system and even formatted and reinstalled Windows… Nothing helps. It’s been fine for 600h with 1 crash, then one update comes and breaks everything.
@CptEvillian Yes I am aware of that but somehow data still gets synced to the steam cloud that’s needed by the exe. It seems to be some config stuff like controller bindings etc. that are on steam cloud and might have been corrupted. Because it’s obviously not my system that can’t run FS2020 it worked for 600h and the store version worked right away too. It’s only the steam version that is broken… Check the thread here for more details: https://forums.flightsimulator.com/t/su5-ctd-on-every-sim-start/427464
