Progress not being saved when playing offline multiplayer

My sister and I have a shared world, but a while ago, the world began to get lazy, the chunks did not load and the entities froze near the area that did not load, in addition to not being able to save the progress, the autosave icon it remains on the screen all the time and when closing the world the save does not advance and thus lasts for hours, we resort to closing the game (we have it physically) from the beginning of the console and when opening it again, it is not possible I had saved nothing, this is how it has been happening to us every time I join the world, we tried to play, move forward and I, the guest, exit first and the host saves and closes but the same thing happens, the save of the world does not advance, I hope this has solution since it is better to play between two
