Hi @fracorbas could you see if your issue might be similar to this one from 8.13? Winlogbeat 8.13.0 dont start service - #6 by tapiojaa
If its the same problem as that topic, 8.13 has trailing / on some of the service paths if it was installed via the MSI. The linked comment has a suggestion on how to fix it, or it should be fixed in the next release.
