KeyError: ~TContext

[Navashub]

I first did the installation from the documentation

pip install openai-agents

then did the imports

from dotenv import load_dotenv
from agents import Agent, Runner

I am on python version Python 3.11.0

and here is the error:

I tried to reproduce the same error, but I couldn't. To make sure if this does not happen in a clean virtual environment, can you run the following commands and see if you still get the same error?

python -m venv .venv
source .venv/bin/activate
pip install -U openai-agents
echo 'from dotenv import load_dotenv
from agents import Agent, Runner' > test.py
python test.py
