OnlyOffice Bug Loading Document 100%

One Document on other User is stuck on “Loading Document: 100%” … I am using https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/insecure/mariadb/apache/docker-compose.yml with onlyoffice & community server app. when i create new document it doesnt have this problem. How can i prevent such a bug ? would it help to disable auto save?
