Hello,
this is resolving to be a user support case. Please go to the mailing
lists as there is still no information why OpenVPN would be at fault
here.

One the first one, I remove all package related to openVPN and retry the
installation following the debian wiki :
https://wiki.debian.org/openvpn%20for%20server%20and%20client
That page sadly didn't get updated in more than a decade. I have added
a warning.
I use the configuration file describe in the wiki execpt this two following
lines :
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf
Please lets see your configuration and also add the infomation about IP
addresses, routing tables etc that I asked for in my initial reply.
One the second one computer, I upgrade my system yesterday since this upgrade
Openvpn don't work any more.
Please also substantiate what you mean by "does not work".
Below the error :

It is a surprise that update-resolv-conf is still called since you say
that you didn't include those options in your OpenVPN config. What is
your DNS setup and how did you plan to include DNS in your setup?
In this case, I use OpenVPN with Openresolv package to avoid dns leak.
Tell me if you need more information.
I would recommend debian-user or an OpenVPN support medium. I can try to
help, but I am not doing user support here, and I need the information I
asked about in my first reply.
I am probably not going to reply to your next message if you don't
deliver the information I asked for.
Greetings
Marc
