Recently ran into this issue running Mellow on windows where a movie title with a colon in it (ex. Jurassic World: Fallen Kingdom) errors out talking to Radarr
{ error: null, body: '{\r\n' + "message": "The given path's format is not supported.",\r\n + ' "description": "System.NotSupportedException: The given path\'s format is not supported.\\r\\n
Adding the movie directly in Radarr works and I have "Replace illegal characters" enabled in Radarr settings
