After update Synology on DSM 7.0.1 Serviio is down

Hello, I own Synology 218j. After updating DSM 6.2.4-25556 to 7.0.1. Serviio is down. It cannot be updated. An error message appears: Invalid file name, contact the package developer. There is some way to reinstall Serviio - step-by-step instructions.
Thank you Milyss
