Save and Quit Infinite Save Screen Bug with Closing Error Nintendo Switch

It appears that my save is corrupted, although my save in its entirety is functional. Upon saving my world, or occasionally even loading it, my game gets stuck on the saving screen (see attached), even after 10 minutes the save doesn't complete, and the only thing that can close Minecraft is closing the software, which it then crashes due to an error (see attached). Randomly, after creating a copy of my world I could save the game, but after I placed some items in a chest, it went back to its prior behavior.

My world type is set to "Old", and no other world, even my other "Old" world encounters this problem. I took a run around my entire world and found no chunk errors or missing chunks.

I have tried hard restarting my Nintendo Switch, using a copy of the world (ended with similar results), destroying some of the empty chests and barrels I had, none proved successful in the end. The only thing that really worked was saving on a different chunk, but I think these save bugs will keep happening, even if the bug is temporarily gone.

Thank you for your time, and please ask me about anything else about my settings or world if needed.
