RecursionError: maximum recursion depth exceeded

[pooryousefshahrooz]

Describe the bug I am running this command: from qiskit_algorithms.utils import algorithm_globals

and getting error:

RecursionError                            Traceback (most recent call last)

Suggested solutions I know another issue has been opened on this but I could not find any response for that. And that is why I opened another one. thanks
