[Question] 'NoneType' object has no attribute 'glfwGetCurrentContext'

Question

Hi！I have some questions for you
background：

gymnasium: 1.0.0
glfw: 2.7.0

I run the code below：

import gymnasium as gym
env=gym.make('Humanoid-v5', render_mode='human')
obs=env.reset()
env.render()

An error was reported ：

  logger.deprecation(
  File "D:\anaconda\envs\Gemma2b\lib\site-packages\gymnasium\envs\mujoco\mujoco_rendering.py", line 359, in __del__
  File "D:\anaconda\envs\Gemma2b\lib\site-packages\gymnasium\envs\mujoco\mujoco_rendering.py", line 352, in free
  File "D:\anaconda\envs\Gemma2b\lib\site-packages\glfw\__init__.py", line 2366, in get_current_context
AttributeError: 'NoneType' object has no attribute 'glfwGetCurrentContext'

When I take the solution given earlier：

import gymnasium as gym
env=gym.make('Humanoid-v5', render_mode='human')
obs=env.reset()
env.render()
breakpoint()

The result of the code run is: The mojoco simulation interface is not responding

You may have to close the env before the program ends.

import gymnasium as gym
env=gym.make('Humanoid-v5', render_mode='human')
obs=env.reset()
env.render()
env.close()

This might be a windows only issue

We don't officially support windows but will try to fix bugs

If you're using Windows, try the Linux subsystem.
