Due to changes introduced in https://bugs.python.org/issue14935 the `csv.Error` can't be subclassed in 3.10. To reproduce:

Python 3.9.4 (default, Apr  6 2021, 00:00:00)
>>> import csv
>>> class C(csv.Error):
...     pass


Python 3.10.0b1 (default, May  4 2021, 00:00:00)
>>> import csv
>>> class C(csv.Error):
...     pass
... 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: type '_csv.Error' is not an acceptable base type
