Blender behaves strange copy shift D wont work, and nearby things als move,

well this is how my screen looks like when i try to move something it comes full of reg/green/blue lines and i cannt copy while in this mode, or i cannot move them as separate objects, i can only copy and move in edit mode :frowning: when i move something nearby objects also move.
Restoring to factory defaults wont help either

It’s because you have proportional edit active.
