Circle rounds the player in game when I add “circle collider 2D”. What to do to remove it from game view??

Try to deselect the Player from your “Hierarchy” or unmark “Gizmos” at your “Game” window tab

See the little triangle on the component?
Click that to collapse the circle collider. The circle should not show up any more.

Okay I think this is what you need, click on that little arrow next to gizmos. Then check all of them in. Then click on gizmos (not the drop down this time). This worked for me.
