Me neither, I had some errors in the past but nothing close to that.

That's what I thought, but the problem is :
ii  cython3        0.29.21-3+b1 amd64        C-Extensions for Python 3

Cython's installed (and to make sure there was no glitch, I reinstalled
it)

As far as I remember, nothing about Python3 was touched or tweaked since
way before BB version 1.1.18.

I also need to be able to make a backup ASAP following big changes in a
appli of mine.
