The problem is with NordLynx, not Python.

Quite impressive that a blank signature needs a "powered by" advertisement.

I found its Git repository using the following method:

$ for i in python-distutils-extra python3-distutils-extra; do apt showsrc $i |& 
grep git; done | sort -u
Vcs-Git: https://salsa.debian.org/python-team/modules/python-distutils-extra.git

Therefore, for developers, the more robust and reasonable pdfarranger 
installation steps should be as follows:

#https://github.com/pdfarranger/pdfarranger#install-from-source
$ sudo apt install gir1.2-gtk-3.0 gir1.2-poppler-0.18 
$ git clone https://github.com/pdfarranger/pdfarranger.git pdfarranger.git 
$ cd pdfarranger.git 
$ pyenv shell 3.8.3
$ pyenv virtualenv --system-site-packages pdfarranger
$ pyenv shell pdfarranger 
$ pip install -U pip
$ pip install 
git+https://salsa.debian.org/python-team/modules/python-distutils-extra.git
$ pip install img2pdf pygobject
$ pip install .

Another note: the python-distutils-extra or python3-distutils-extra is only a 
dependency in the installation process, once the package is installed, it will 
no longer be needed.

use git blame to find out the commit then use git log to read the commit 
message.

Re: recover pickled data: pickle data was truncated

At work and personally I use iso-8601 timestamps to make the files unique and 
easy to
find out when they where created.

:>>> t = datetime.datetime.now()
:>>> t
datetime.datetime(2022, 1, 2, 12, 34, 1, 267935)
:>>> t.strftime('%Y-%m-%dT%H-%M-%S')
'2022-01-02T12-34-01'
:>>>

That is good enough as long as you create the files slower than once a second.

Oh and yes use JSON, it is far better as a way of exchanging data than pickle.
Easy to read and check, can be processes in many languages.

 I agree with Barry, Chris and Avi. IMHO your data is lost. Unpickling
 it by hand is a harsh work and maybe unreliable.
 
 Is there any reason you can't simply add a semaphore to avoid writing
 at the same time and re-run the code and regenerate the data?
