Just updated Instapy, but this is the result

Traceback (most recent call last):
File "/home/pi/InstaPy/assets/script.py", line 34, in
with smart_run(session, threaded=True):
File "/usr/lib/python3.7/contextlib.py", line 114, in __enter__
raise RuntimeError("generator didn't yield") from None
RuntimeError: generator didn't yield

```

assets/script.pyから開始し、特にトレースバックに示されているエントリポイント smart_run(session, threaded=True) を確認します。利用可能であれば、timeoutのログと生成された /tmp/20210714-103831.html ファイルを比較し、その後、visibility waitの後にコンテキストマネージャーがyieldしない理由を追跡します。timeoutの原因を特定して再現し、quickstartセッションが完了することを確認できれば完了です。
