Francil - i had the same issue, with loading screens ( while saving, loading a map, etc..) and the best workaround i found was to save exactly in front of where you wanted to go. So try saving just in front of the bridge, quit the game, relaunch it and try again from your last save.
That's how i'm bypassing the save game crash issue, and how i managed to get to HOmestead / end times for the first time. The game would crash during load screen for homestead / EOT wherever i tried to access it from (healer's house, burning field @ church, room at the inn in Cyseal). So i saved a the game just in front of the room @Cyseal's inn after asking the guard to open the door. Left the game, relaunched it, entered the room directly and it worked).
