CTD when editing apron materials on my airport

It doesn’t crash as soon as i start changing the materials on the apron grass
in this case but seems to after say 20-30 mins messing about with it the sim
will suddenly lock and CTD only seems to happen when editing apron textures.
extremely frustrating having to redo a section every time this happens.
getting to point will have to save the project every time place an apron

Hi, did you manage to solve it? I got the same starting today after I
installed the latest Nvidia driver, I rolled back the driver to the previous
version but no luck so far I can do anything in the sim but not with SDK…
