PlayerController Script Causing Terrible Performance (Profiler says FixedUpdate: LogStringToConsole)

I've been using this player controller script since I first started working on my game, and it's never given me issues until now. The profiler says "PlayerController.FixedUpdate() > LogStringToConsole" is taking up about 96.3% of CPU usage--at least that's what I think it means.

Here is the script:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerController : MonoBehaviour
 {
 
     public float maxSpeed = 10f;
     public float hold;
     public bool facingRight = true;
     public bool cantMove;
 
     Animator anim;
 
     public bool grounded = false;
     
     public Transform groundCheck;
     float groundRadius = 0.2f;
     public LayerMask whatIsGround;
     public float move;
     public float jumpForce = 700f;
   
     void Start()
     {
         anim = GetComponent<Animator>();
         hold = maxSpeed;
 
     }
 
   
     void FixedUpdate()
     {
         
         grounded = Physics2D.OverlapCircle(groundCheck.position, groundRadius, whatIsGround);
         anim.SetBool("Ground", grounded);
         anim.SetFloat("vSpeed", GetComponent<Rigidbody2D>().velocity.y);
 
         move = Input.GetAxis("Horizontal");
         anim.SetFloat("Speed", Mathf.Abs(move));
 
         GetComponent<Rigidbody2D>().velocity = new Vector2(move * maxSpeed, GetComponent<Rigidbody2D>().velocity.y);
 
         if (move > 0)
             FlipRight();
         else if (move < 0)
             FlipLeft();
     }
 
 
 
     void Update()
     {
         if (grounded && Input.GetKeyDown(KeyCode.Space))
         {
             anim.SetBool("Ground", false);
             GetComponent<Rigidbody2D>().AddForce(new Vector2(0, jumpForce));
         }
         if (cantMove == true)
         {
             maxSpeed = 0;
         }
         else
         {
             maxSpeed = hold;
         }
     }
 
 
  
     public void FlipLeft()
     {
         Vector3 theScale = transform.localScale;
         theScale.x = -Mathf.Abs(theScale.x);
         transform.localScale = theScale;
         
 
     }
     public void FlipRight()
     {
         Vector3 theScale = transform.localScale;
         theScale.x = Mathf.Abs(theScale.x);
         transform.localScale = theScale;
 
     }
 }
 

I don't have a Debug.Log statement in this script, so I'm unsure of what the profiler means by "LogStringToConsole" in this instance. When I disable the PlayerController script, everything runs very smoothly. However, as I said, I've had this script in my game for a while, and everything has run fine before now.
