Unreal Engine 5 crashes immediately when trying to load assets

Unreal engine 5 was working until i imported a 20 million polygon car (Not mine, i am forced to use it by my boss) and assumed i could nanite it but it would crash when attempting that. So i decided to try to deal with the lag of it in the scene and just rebuild some materials for it and when i applied a material with translucency it crashed immediately.

Now it will open and i can move the camera around before it tries to load assets then it crashes and gives me this error below. What can i do? Deleting the car and new material does not prevent the crash but it still opens and is useable until unreal engine tries to load assets
