Hello!
We see two different problems. The first one is caused by OpenVPN: apparently it has been built with an hard coded wrong path to ip:
. 2022.11.13 16:34:09 - OpenVPN > /bin/ip link set dev tun0 up mtu 1500
. 2022.11.13 16:34:09 - OpenVPN > Linux ip link set failed: could not execute external program
. 2022.11.13 16:34:09 - OpenVPN > Exiting due to fatal error
As we can see from what Eddie log entries, you have ip in /usr/sbin. Eddie locates and runs it successfully, for example:
. 2022.11.13 16:34:09 - Elevated: Exec, path:'/usr/sbin/ip', arg:'-4', arg:'route', arg:'show', exit:0, out:'default via 192.168.0.254 dev enp5s0 proto dhcp metric 100
Please create a symbolic link from /bin/ip to /usr/sbin/ip, or copy the ip file in /bin too, so the first problem will be resolved.
Then, another problem is visible:
W 2022.11.13 16:34:09 - Unexpected: Network interface unknown - Stack: at Eddie.Core.ConnectionTypes.IConnectionType.SearchTunNetworkInterfaceByName (System.String id) [0x00066] in <2af199c257ac4ca1aad2d2fb8c81a0e5>:0

This might be a critical problem as well (try again anyway when you have solved the 1st problem).
If the problem persists or any other issue comes out, can you send us a system report generated by Eddie, to let us can check various settings, including network interfaces?
Kind regards
