Any idea what’s gone wrong with my game?

https://www.reddit.com/r/SkyrimModsXbox/s/jdw252OCHt I’m using the same load order as this one yet for whatever reason going anywhere near the outside of white run just crashes my game, which is strange since I’ve been using this LO for a while and have had no issues, they just randomly started, maybe too much of an ask but help would be greatly appreciated
