minecraft worlds unable to load and not update to on saves yet the game has all my purchases on character stuff etc up to date my skin is fine and my achievements are all up to date as i have them all etc

only just a day ago i was playing the game normally enjoying my long lasting survival world on my xbox but as of yesterday night (it’s the next morning as i write this) i loaded up my xbox and my Minecraft was said to need a update so as it is the game “began” updating the progress bar didn’t go up after some time so i decided to restart my xbox which once done the progress bar of the update went up and so on and so on until it was “ready to start”/ completed update so we you do i clicked the game to load it however this time the start up was different it was asking me “first time player questions” like do i want narrator on and wot do u want to set your safe zone etc etc. Even though the game remembered and saved all my achievements and skins as seen in the files attached my worlds weren’t there the only worlds i had access to seeing were black and white thumbnail-ed again as seen in my attached files and the saved were from 2021 and 2020 and my recent worlds were gone. I’ve lost my hard-work and comfort of my multi year worked on world which it’s now gone and did cause me great distress seeing it’s gone so in the simplest from i’m asking for support on getting access to my worlds like normal again as i don’t rlly want to start a new world as the memories i have attached to this world too it’s tremendous thank you ! i was told by one helping to uninstall and then reinstall yet a post later made after that advice said not to do so especially if your saved data is over 4gb. the game remembers my skin and stuff everytbing is uodate apart from my worlds are gone which is devastating
