Windows 11 WHEA ErrorSource control via WMI is broken

The WMI call to disable a WHEA ErrorSource is broken in Windows 11 while it works properly on Windows 10.

The Sources accept the command and are changing status to Stopped but they still log errors as if they aren't stopped.

This is an example C# code:

public int DisableSource(ManagementScope scope, int ErrorSourceId)
        {
            try 
            {
                ManagementObject obj = new ManagementObject();
                ManagementPath path = new ManagementPath(scope.Path + ":WHEAErrorSourceMethods.InstanceName='WHEA_WMI_PROVIDER0'");

                obj.Path = path;
                obj.Get();

                ManagementBaseObject inParams =
                    obj.GetMethodParameters("DisableErrorSourceRtn");

                inParams["ErrorSourceId"] = Int32.Parse(ErrorSourceId.ToString());

                ManagementBaseObject outParams =
                        obj.InvokeMethod("DisableErrorSourceRtn",
                        inParams, null);

                WHEAservice.WHEAService.EventMsg("Status=" + outParams["Status"].ToString());
                
                obj.Dispose();
                
                return int.Parse(outParams["Status"].ToString());

            }
            catch (ManagementException e)
            {
                #if DEBUG
                    WHEAservice.WHEAService.EventErr("Failed DisableSource for " + ErrorSourceId + ", WMI exception thrown: " + e.ToString());
                #endif
                return 5;
            }
            catch (Exception e)
            {
                WHEAservice.WHEAService.EventErr("Failed DisableSource (this can be normal) for " + ErrorSourceId + ", exception thrown: " + e.ToString());
                return 5;
            }
        }
