2D Cast Problem

hey! im trying to set up a collision system for my 2d platformer and I cannot get this code to work but I dont know why:

 //Collision Check
 int col_hits = col.Cast(velocity,contactFilter,collisions,velocity.magnitude);
 float dist = collisions[0].distance;
             
 if(col_hits != 0){
       velocity = Vector2.ClampMagnitude(velocity,dist);
 }
     
 //Move Player
 transform.Translate(velocity.x,velocity.y,0);

Basically I want it to do a "cast" then move itself to the position where the collision occured, however the result I am getting is that the character is moved just so that it intersects with the collision and is stuck there forever.

Any ideas would be super helpful!
