ZenAdminSrv not starting anymore

ZenAdminSrv not starting anymore

Hello, on a plant installed a year ago, my customer has a problem when starting one server. The message box "Waiting for service ‘zenAdminSrv" appears when starting the project. The message box does not disappear and the project never starts. I asked them if there were any changes made on the computer (it was working well during the commissioning). They ensured me nothing changed on the computer so I asked them to use the System Information Collector to make an archive so I could send it to the support. I have the zip file (see the attachment). Could anyone help me on this please?
