After coming to an end of what I could test to make this error stop I started reading about people reinstalling their sim due to possible corrupt installations from the first day problems with the launch. I was one of the first ones to actually get a download and get into the sim but I did get hung up forever at 97% before I did.
Anyway with the speed at which you can install now I thought that I definitely could have a corrupt install so I decided to uninstall and reinstall. 2 nights ago after installing I was able to fly the Cessna 172 for over an hour with no crashes. This was completely vanilla sim with no addons active. Tonight I downloaded the latest patch and then tried another flight this time with my Navigraph stuff active in the sim which I had been using before. I had another successful flight with the C172 of over an hour. Previously this error would happen around 20-30 minutes in. I also noticed improved smoothness in VR after reinstalling.
I can only say that this worked for me and if you think that you might have a corrupt installation at all I think it’s worth a try to see if it will clear up these problems.
