[BUG] Crash on Render

**Describe the bug**
Blender crashes on render when Scene Node is present in the network & realtime update is checked (nodes turn red before crash).

**To Reproduce**
1. Create a new nodetree
2. Make a simple network with realtime update set to True
3. Press F12 to render out image (or animation)

**Expected behavior**
Render with the updated mesh

**Screenshots**
-

**Desktop (please complete the following information):**
- OS: Windows, Mac (Mojave)
- Blender Version: 2.81, 2.81a
- Sorcar Version: 3.1.2

**Additional context**
If the Scene Info node is connected without realtime, the values no longer update when an animation is rendered out so the object no longer animates.
