if the obj object has more than 1000k vertices,use the build-in obj importer will be very slow sometimes take half an hour since it is written with python.
I written this OBJ importer using C++ code.it is much faster than the python implement.
although it not be optimized with code. I will continue improve the speed of import in the next version.
there is no exporter currently , but will make it.
import 10000k face obj takes about 1 minutes(7 time faster than the build -in importer)

Why not submit this to https://developer.blender.org ? So it is included in the trunk. However I am pretty sure that you will need to reformat your code so it is in English only.
I will put all the code to GitHub when it become stable.
the reason it will get error, is I don’t consider all the data of obj , some data like material or group are not read now.
do you using the newest version of addon? or your obj file path is not full English?
can you give me the full path of your obj file? (not obj file) I need to know the file path.
And Yes I using the latest 20191205 version, and the file path is very simple just as a dirve name like as “C:”, and of course the file name is full English as well.
