Crashing When Traveling

Xbox 1 player, my most used large save file wont allow me to travel without crashing.

Cannot complete the quests because everytime i try to leave my home lot the game crashes and I have to load everything again. I have 5 sims in my household and a pregnant Sim there are many items in the home I tried deleting a bunch so the game wouldnt glitch/crash so often, it hasn't worked. Do I need to start a new game, is there away around this. To my knowledge this wasn't happening in beginning of January but I haven't played much since then.
