Python: Crypto package error: "No module called '_number

I have a software which installs its own local Python 3.9. Included in its python39/lib/site-packages is Crypto package, which causes errors and seems old and incompatible with Python 3.9. It includes long integers, like 1L, which I fixed by removing the "L". But I'm still getting the error below, even though the file

...\python39\lib\site-packages\Crypto\Util\_number_new.py

exists. For now, I'm trying to fix such errors manually, to avoid dealing with other incompatibility issues that will show up, if I try to update the whole Crypto package. The line in number.py:

# New functions
from _number_new import *

Error message:

Modules in packages can be accessed using dot notation, so you just need to:

from Crypto.Util._number_new import *
