Minecraft Won't Update

This isn't for everyone, but on the help discord, I realised a few also experienced this bug. I don't know if it's for version 1.16.20 or 1.16.10 since I'm playing 1.16.10 but it's 1.16.20 I can't connect to. I tryed many different thigs without luck. I'm thinking about uninstalling and reinstalling Minedraft but I'm scared of loosing my data. I backed my worlds up on in a seperate file, but still. I would like help on what to do, especially how to save all my Minecraft Bedrock data without risk loosing it.
Thanks
