weird problems in unity

so I was actually having these problems from the last month but since i spent most of it without even opening my project...but it's really problematic now.....

the problem is that -

1. anchors (in the scene view) and anchor options(in the inspector) no longer show up

2. attributes like header and range have stopped working although they did work before and i haven't changed the scripts....an example

the script on this one is just

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class AttributesNotWorking : MonoBehaviour
 {
   [Header("test")]
   public string test;
   [Range(0, 5)]
   public int testnum;
 }

i have no idea why this is happening, and i basically can't properly set anchors for the ui in my game

Any and all help is appreciated...Thank you!
