Weird issue with UI and Sprites?

Hello, I am having a really weird issue with some UI and sprites. The part were it is weird is that everything was working normally and on a sudden it simply stopped working. The sprites or gameobjects in general in my UI canvas stopped being able to be dragged and moved around, also a specific sprite is not showing any more when going to play mode.

As you can see the arrows on the movement for dragging an object are not there anymore and for some reason the sprite of the rock isnt appearing at all on the game itself. It gave me the same issue with the battle stations (green grounds) where the enemy and player should be. The fix that I did literally was to close and reopen Unity and then it worked. However now that I did it again it is crashing even more.

Check if the rock is in the camera view.
