ERROR: Default framebuffer is not complete, error 0x0

Tried to call MjSim.render() but had an error message:

>>> sim.render()
Found 1 GPUs for rendering. Using device 0.
ERROR: Default framebuffer is not complete, error 0x0

MjRenderContext gives;

>>> ctx = MjRenderContext(sim, offscreen=True, opengl_backend='glfw')
Creating offscreen glfw
ERROR: GLEW initalization error: Missing GL version

Though I can render offscreen mode by this work around. #187 (comment) I'm continously generating new MjSim object. This way I get a lot of OpenGL window which I can't close within python, not solving my problem actually.

It was fine previously when I use an older version of nvidia driver. Now the Nvidia-410 uses OpenGL 4.6
