I see you are using python3.8, can you try with a >=3.10?

[BT-crodriguez]

@nilshamerlinck I tried with 3.12.7 and it worked, i didnt see this change of requirements anywhere and it's not on the develop.rst...

Thanks for the help

I had the same issue when trying with Python 3.8. Upgrading the Python requirement would be nice.
