• platform: windows 10
• python version 3.12.1
• pyglet version 2.0.10
• OpenGL version 4.3.0 NVIDIA 536.23

Please check out your OpenGL version support. The gl.glBlendFunci is supported for OpenGL >= 4.0. The version restriction should be applied in toplevel/window.py.

To check out the gl version of the context attached to the created window, after the window creation insert this line:

print(pyglet_window.context.get_info().version)

Ideally it should print out 4.3.0.

By the way, what's the platform you are using? It's known that manim3 does not support macOS (for its end of support on OpenGL).

Thanks for your reply. My platform is Windows 10 and OpenGL version is exactly 4.3.0

Sorry but it seems I cannot bring any help further. My configuration is almost identical with yours, but I cannot reproduce your exception.
