I am unable to move object in object mode, reinstalled/restarted blender but only the pivot point is moving not object. i don't know why? Blender error: when i installed blender first time, i used transform tools (move/scale/rotate) but the problem is only the pivot point is moving in object mode i can't move overall object in it. In Edit mode i can move all(vertex/edge/face). i don't know How to solve this problem.
You probably have Affect Only Origins enabled. Disable it by pressing Options in the top right corner of the 3D viewport &gt; Origins

You can also disable it by pressing the Active Tool and Workspace Settings tab in the Properties bar, and press Origins.
