This is my project for work. Example projects I’ve downloaded from UE work as expected. When I open this project though (which does work for the rest of the team, although I think all of them are on windows), it crashes as soon as the cursor enters or interacts with the viewport. I can’t tell much more about the crash, other than from reading the log (which I’m posting the relevant part of, along with the screenshot showing my macbook specs below) is that it seems that possibly the metal material is crashing the graphics card?
