Blender freeze after hair particle system really strange but im not able to duplicate the particle system from the left wing to the right wing without crashing blender.
I used ctrl + m, x to mirror the wing, maybe some bug here? Also used https://blenderartists.org/t/boundary-aligned-remesh/1149739 to remesh the wings.
i was not able to reproduce the error.
Best, Joseph

If the color in the Viewport Shading is set to Random it will crash, if it set to Material everything works fine.
