NullReferenceException thrown when using HandleUtility.DistanceToPolyLine

Hi!
We have a custom editor window in our team that works well in Unity 2108.4
I tried upgrading our project to 2019.3 in order to check if our custom editor would need some update for this version and I'm facing a weird error :

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. UnityEditor.CameraProjectionCache..ctor (UnityEngine.Camera camera, System.Single screenHeight) (at <6f28216fea9f453abf2e05b770ed3ee4>:0)
3. UnityEditor.HandleUtility.DistanceToPolyLine (UnityEngine.Vector3[] points) (at <6f28216fea9f453abf2e05b770ed3ee4>:0)

I've tried restarting my computer and Unity (that seemed to resolve related errors in previous versions from what I gathered on the internet) but no luck so far.

 

Any chance you managed to find a fix for this issue in the end?

 

As a follow up, we ended using the old implementation of the method in our code :

Code (CSharp):

1.         // We use the old implementation. Changed in Unity 2019.3 and throwing NullReferenceExceptions
2.         public static float DistanceToPolyLine(params Vector3[] points)
3.         {
4.             if (points == null)
5.                 throw new ArgumentNullException(nameof(points));
6.             float dist = HandleUtility.DistanceToLine(points[0], points[1]);
7.             for (int i = 2; i < points.Length; i++)
8.             {
9.                 float d = HandleUtility.DistanceToLine(points[i - 1], points[i]);
10.                 if (d < dist)
11.                     dist = d;
12.             }
13.             return dist;
14.         }
