The sidebar link this plugin adds to Jellyfin's nav is injected by registering with the File Transformation plugin once, at Jellyfin startup. That registration was racing File Transformation's own startup init, so on some restarts (including scheduled ones) it silently failed and the link just never appeared, with nothing in the logs beyond a generic, undiagnosable error. Registration now retries a few times before giving up, and a real failure logs the actual cause instead of a useless wrapper message.
