Steps to reproduce:

1. Create a new URP Project with OpenGL set as Graphics API
2. Enter Play Mode
3. Open Preferences for Shader Graph and toggle "Open new Shader Graphs automatically"
4. Create any ShaderGraph Asset
5. Exit Play Mode and Repeat steps 2-4 five to 6 times

Actual results:

When repeating steps 3-4 whilst in Play Mode, UI will break and start artifacting, Editor will have to be reloaded, Error is spammed: "Layout update is struggling to process current layout (consider simplifying to avoid recursive layout)"

Sometimes Error is logged: "ArgumentException: Getting control 0's position in a group with only 0 controls when doing repaint Aborting"

Expected results: Creating ShaderGraph Asset in Play Mode does not break Editor UI

Reproducible with versions: 6000.3.0b8, 6000.4.0b8, 6000.5.0a6

Can't test with: 6000.0.67f1 (No Preferences option feature)
