Can only move object origin in object mode, cant move the mesh I can only move the origin point of the mesh that I selected in object mode, but not the whole mesh
Did I set anything up by accident?
You have likely enabled the Transform Affect Only option for Origins by accident. This can be disabled in the Options dropdown located in the header of the 3D View. Alternatively you can find the same option in the sidebar (N) under the Tool tab in the Options panel as Jachym Michal noted.
