Came here to see if there was anything similar to my experience - and found it!
I'm using MSFS 2020 and have had CTD 4 times, trying to use the VA livery A350-1000, attempting to load into gate 320 at Heathrow (inibuilds version)
In my case I am getting about 20 seconds into the loading screen after hitting the fly button then CTD.
First time this has happened to me, I updated the plane last night.
Im on a 5800x3d, 4070ti and 32G Ram.
