I am rolling back to 3.8 which works, but thought you all would like to know,

Thanks for the report. greenlet 0.4.13 does not support Python 3.8 or newer; it was last updated for Python 3.7 back in 2018. Support for Python 3.9 was added in greenlet 0.4.16. The current release of greenlet is 1.1.2 which supports up to Python 3.10.
