Description
Description of bug / unexpected behavior
Using the latest main branch, run manim render --renderer opengl -p .\example_scenes\basic.py OpeningManim to render the example scene with OpenGL, an error occurs.
Expected behavior
The animation should render successfully.
How to reproduce the issue
