TAdvTreeView exception on expanded node in Win11

latest UI Pack
Win 11
Delphi 11.3

Following code works fine an a Win10 OS, but crashes on Win11:

for i := 0 to MyStrList.Count - 1 do
    begin
      n := MyAdvTreeView.AddNode(nil);
      n.Text[0] := MyStrList[i];
      n.Extended := true;
      n.Expanded := true; // <- access violation 
  end;

Please first add all nodes between BeginUpdate & EndUpdate, and then afterwards Expand/Collapse them.
