Sadly I am having the exact same issue. Older saves work newer saves do not.
Summary: After playing many hours in game, while travelling on map the game crashed. This has happened before in another campaign, so I made a whole new one and it has happened again. Upon trying to load last save as well as older saves the game crashes during loading. If I go back to a really old save it loads fine, but it would mean doing things over again... which I did and sure nuff it happened again.
How to Reproduce: Play the game long enough and try to load recent save.
Have you used cheats and if so which: I enabled cheats by changing the 0 to a 1 in the game folder. I mostly just heal my horse and myself during battles. I also use Mods.
