When converting GPv3 object with zero drawings to curves, Blender crashes due to accessing invalid drawing/offset value. With `curve to mesh` node, the evaluated `gemoetry_set` had a dummy GPv3 object data with zero drawings, see `BKE_grease_pencil_data_update`. Hence, the crash in `object_convert_exec` while accessing the offset array. Pull Request: https://projects.blender.org/blender/blender/pulls/123067
