There's no error message, the game just stops responding after you to load the save or continue it? First thing to try would be to let it sit for a long period, say 10-15 minutes, to see if it's not something that's causing an unusually long (but possibly temporary) delay in loading. If that doesn't work, we'd need to see one of the saves to check for damage - see
