Realm crash and rollback

Despite the 1.13.1, Realms on Bedrock version are still crashing and rollback to the last automatic save. Disconnection every 5 minutes, always unplayable (but still payable!)

It seems to work (don't know how many time) when you open a new Realm with a new world...

My world worked well on 1.12 and became unplayable since 1.13
