I recently upgraded to CoreELEC 9.2.
On the next reboot, it seems the VPN settings were lost and I had to go through the Wizard again. When I did, I get "Error updating .ovpn files or creating user credentials file. Check log to determine cause of failure".
In the log, I see:
"ERROR: CAddon[service.vpn.manager]: failed to load addon settings from special://profile/addon_data/service.vpn.manager/settings.xml"
That file exists but it is empty.
And also from the log:
