Old Campaign Save Game bug crash is back

Was doing a campaign on the second chapter of Sforza where I saved once. I saved it before I marched my troops into one of the cities, notably I reused the save multiple times to prevent my losses so basically the save game got spammed. However, one time it got used, it crashed my game. So I reopened the game and the save file and now it keeps crashing everytime I try to load it! Please advice what I should do.
