This should be due to a version mismatch, downgrading to gym 0.21.0 should solve the issue:

pip uninstall gym

pip install gym==0.21.0

@anyboby Thanks, yes you are correct, gym-minigrid currently doesn't support the latest gym version. That is in the works. Gym v0.23.0 should work fine, let us know if that is not correct
