Error opening configuration file: openvpn closes connection and kills container about docker-jackettvpn HOT 5 CLOSED

It does indeed seem related to the issue you shared.
Did you try this yet?
Unchecking "execute container using high privilege" and re-checking it again fixes the issue with DSM 7.0 after migration.

And, did you also try other solutions of that issue, like this one?

I found the fix and already posted it in the mentioned qbittorrentvpn issue, but I thought I'd put it here also.

Add the following lines to your compose file:

  devices:
    - /dev/net/tun

from docker-jackettvpn.

Please refer to this issue for a solution, as @SheepKid12 also mentioned:

I have the same problem even after trying the solution from the other posts...

Same. My yaml is identical to yours and I get the same read error about the openvpn config file.

Made sure to add the cap_add: - NET_ADMIN and privileged parameters.

Interestingly it worked for my transmission docker instance but not jackett.
