Can't rotate the scene view or move objects anymore

My scene view camera is locked ! I can move with the arrow keys or WASD keys while pressing the right mouse button, but it won't rotate anymore with the right button clicked, and dragging with the hand tool doesn't work either.

Furthermore, I can't move gameObjects in the scene view by dragging them (only by changing the transform values)

I have checked/tried the following :

• the view gizmo is not locked

• I am in 3D mode

• I've tried focusing on different GameObjects (doubleclick/F)

• I've tried with every tool (hand, move, rotate etc.) selected

• I've tried closing/reopening unity

• I've tried creating a new scene and loading it

• I've tried closing and reopening the scene view

• I've tried loading a different project where i never had the problem (the camera is locked there too)

• I've tried playing the game then stopping it

• I've tried uninstalling and reinstalling my version of Unity

This is very frustrating, help would be appreciated !
