Sim crashes when adding runway

I’ve tried this about 10 times by now. Whenever I add a runway, and try to move it and orient it, the sim crashes. It seems like it has to do with the elevation changing when adding the runway. I’m brand new at this, and I’d like to see if there’s a way to add the runway but not effect the height map. I’d like for it to just follow the terrain since it’s a gravel strip.

Thanks for the help.

try to update the SDK, remove the old one and install again.
