Testing

it works with render_mode="human" `render_mode="rgb_array"

import gymnasium
import mujoco
import time
from gymnasium.wrappers import HumanRendering, RecordVideo

env = gymnasium.make("Ant-v5", render_mode="human", visual_options={mujoco.mjtVisFlag.mjVIS_CONTACTPOINT: True, mujoco.mjtVisFlag.mjVIS_CONTACTFORCE: True})
# env = gymnasium.make("Ant-v5", render_mode="rgb_array", visual_options={mujoco.mjtVisFlag.mjVIS_CONTACTPOINT: True, mujoco.mjtVisFlag.mjVIS_CONTACTFORCE: True})
# env = HumanRendering(gymnasium.make("Ant-v5", render_mode="rgb_array", visual_options={mujoco.mjtVisFlag.mjVIS_CONTACTPOINT: True, mujoco.mjtVisFlag.mjVIS_CONTACTFORCE: True}))
# env = RecordVideo(env, video_folder="./save_videos1")
env.reset()

for _ in range(1000):
    env.step(env.action_space.sample())

env.close()

Testing locally the HumanRendering and RecordVideo work great
