I’ve been using UE 5.3 for my project pretty much for as long as 5.3 has been out and never had this crash message appear. I wanted to upgrade to 5.4 for the performance gains, but unfortunatelly more than half the time I try to enter play mode the engine crashes and gives me this message. Anyone knows what might be the cause of this?
edit: so far I managed to discover that this is caused by nanite tessellation but still don’t know how to fix this, whenever I try to load in a level that has meshes that use nanite tessellation there is a good chance I will get this crash.
The same is true if I change tessellation settings in the mesh material (like for example the magnitude of the tessellation), once I hit apply on my changes there is also a good chance a crash will occur.
In 5.3 I also have been using nanite tesselation, but without any problems
