Question Player Stuck Moving

I've been having this weird problem in Unity where my player keeps moving forward and left as if the W and A keys were stuck. This issue occurred in 2 microgames, the universal render pipeline, and a 2D game with custom code (player just moves left in 2D). I am still able to move the player, but if I let go of keys, it continues to move. In the microgames and pipeline, the problem was only solved if I clicked "maximize on play" then stop and restarted the game. I had no problem playing these same microgames on a different PC. In the 2D game, the issue would stop the second time I tested the game, but if I switched windows and game back, the player would move as soon as I started the game (without me pressing anything). This would occur even if my keyboard and mouse was unplugged. I have also tried reinstalling Unity and Visual Studio as well as restarting my PC. I don't think the issue is with the code or my peripherals, and I have no idea what else it could be.

I would really appreciate some help!


Here is the code from the 2D game if you wanted:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class PlayerMovement : MonoBehaviour
4. {
5.    public float speed;
6.    private Rigidbody2D body;
7.  
8.     private void Awake()
9.     {
10.         body = GetComponent<Rigidbody2D>();
11.     }
12.  
13.     private void Update()
14.     {
15.         body.velocity = new Vector2(Input.GetAxis("Horizontal") * speed, body.velocity.y);
16.  
17.         if (Input.GetKey(KeyCode.Space))
18.             body.velocity = new Vector2(body.velocity.x, speed);
19.  
20.     }
21.  
22. }
23.
