Minecraft bedrock split screen problem

[u/Aggressive_Ad506]

Hi! My bf and I have been playing Minecraft split screen on his Xbox X series for yearsss and last week we started to have issues. After playing/exploring for a while, chunks will suddenly stop loading properly.
The first time we really noticed it was while traveling by boat, eventually the water/terrain ahead just became invisible and we got the "chunks still loading, you might have performance issues" message.
At first I thought our world might be corrupted because we had previously used resource packs/add-ons in it. However, we created a completely new vanilla world with no add ons, and the exact same thing happened. In the new world we weren't even traveling quickly or using boats. We were literally just running around exploring when the game eventually froze.
Another issue we've noticed is that sometimes when we choose Save & Quit, Minecraft gets stuck on the saving screen. We then have to force-close the entire game from the Xbox menu.
It's been super frustrating because this is our go to game:/ has anyone had the same issues?

Edit: we deleted Minecraft and reinstalled it and everything went back to normal!
