Bug Help with a red warning "Resolve of invalid GC handle" (UNRESOLVED)

Hi, I recently did 2 new things and started getting an error that I have no idea how to get rid of? Maybe it is not even connected to these but:

I updated to Unity 2020.3.39 and tried out the built in screenshot capture with the code below (I got rid of this script and the error is still there):

Code (CSharp):

1. #if UNITY_EDITOR
2. using UnityEditor;
3. using UnityEngine;
4. public class ScreenshotGrabber
5. {
6.     [MenuItem("Screenshot/Grab")]
7.     public static void Grab()
8.     {
9.         ScreenCapture.CaptureScreenshot("Screenshot.png", 1);
10.     }
11. }
12. #endif

and now the error warning stacktrace:

Resolve of invalid GC handle. The handle is from a previous domain. The resolve operation is skipped.

Found a submit on issue tracker, that after upgrading to 2020.3.39 this same warning started showing

https://issuetracker.unity3d.com/is...en-exiting-play-mode-after-creating-a-tilemap

 

Again this error but was not using Screenshot functionality, just editing prefabs...
(Still on 2020.3.39)
