IndexOutOfRangeException on right click of a Flag Enum field

[AntonioHR]

Describe the bug
If I have a an enum field where the enum has the System.Flags Attribute, right clicking it results in an IndexOutOfRange Exception

Expected behavior
The right click menu should appear

Code Sample

// 
  public class TriTest : MonoBehaviour {
      
      [Flags]
      public enum Flag {
          A = 1,
          B = 1 << 1,
          C = 1 << 2
      }

      public Flag f = Flag.B | Flag.C;
  }

Desktop: Windows 10
Unity version: 6.000.0.18f1
Tri Inspector version: 1.14.1

Here's the error log

IndexOutOfRangeException: Index was outside the bounds of the array.

Just noticed that you're supposed to use this with the TriInspector.EnumToggleButtons Attribute. That results in it not giving the error, but also not opening the context menu.

It's particularly problematic if you want to revert the enum's value to prefab default
