ImportError: cannot import name 'MaxForceErrorHandler' from 'custodian.vasp.handlers #3

Dear Sir
I met an error (ImportError: cannot import name 'MaxForceErrorHandler' from 'custodian.vasp.handlers' (/home/legion/anaconda3/envs/pygwbse/lib/python3.9/site-packages/custodian/vasp/handlers.py)) when I perform create_workflow.py under the folder of example.
How should I fix this error?
Yours
Liang Zhang
