Problem. No access anymore after change

Hi,

I’ve running 2023.5.3 on a Intell NUC. After a reconfiguration of the configuration file I have no access anymore. Via the command line I want to restore a backup. There are a lot of them. How can I see the latest ? Can I only put the config files back? I’ve tried with “backup restore c03f4733” to restore one. Processing …. Done then Error : Unknow error, see supervisor

Who can assist

Thanks
