For people who would be in my case, i posted information that i put here too :
After doing the rounds on the forums and some research on internet, it would seem that the problem of CTD will come from the encryption of the file on the part of Microsoft and/or Asobo.
At this level i don’t really know what else to do, i have already reported the problem on the forum in the bug section.
Obviously for some, the plane does not have problem and others like me cannot fly with it, it could come from the number of dlc install, which would come into conflict.
I personally made tests to delete a lot of my dlc but nothing helped.
To date it seems that the only solution would be to uninstall and reinstall the plane and try again and see is this time it works, otherwise all that remains is to wait for a potential fix with a sim update.
