if you import a MeshInstance3D plane with high subdivision count then you drag the .blend file to the scene you get a Node3D and as a child the MeshInstance3D, if you click the latter, the editor crashes immediately, always happen. I'm just trying to import a sculpted terrain plane and i need to click it to add trimesh, i know i can do it through the reimport tab by making it into a physics static body with trimesh collision but still i need to click the node for various other reasons, like materials etc
in the image you can see the plane vertices/faces count and it is not enough to crash.
would downgrading a version or two solve it?
