I have been playing msfs 2020 since its launch. On and off, there are issues with sim updates, I have either reinstalled or followed steps suggested in the forums or youtube or by asobo team. After I downloaded and installed sim update X through store and started the sim, it progressed to update screen and when i tried to download as suggested, msfs 2020 crashed to desktop. Thereafter, i tried many a time, but failed and CTD was the result. Again, I unistalled and reinstalled through store, sim progressed smoothly till update screen and there was an update of 125 gb size downloads suggested. When tried to download, CTD is the result. inspite of my best efforts through browsing the forums and youtube, i could not update it. MSFS 2020 is installed on SSD with an empty space of 681 gb. I can install all other programs and they have been running successfully. Even msfs 2020 is starting smoothly till update screen and thereafter only it CTD. Forum members, please suggest workaround to resolve this problem.

If the problem persisted through a reinstallation, then it is likely you have something on your disk drive that is messing it up. Try to start a flight with an empty Community folder after deleting the scenery indexes, the shader cache, and  the rolling cache if you can get to the start screen.
