This is the second time I started the Dark Brotherhood questline and again I got the same result. So I guess starting from an early save (in this case the start of the Dark Brotherhood questline) does not fix anything.
Does anybody have an idea for a fix or workaround?
Edit: I checked the size of my savegames and they are all 18 mb. So I guess, from I read in other threads, this might the reason for the crashes.
Maybe Bethesda should deliever a tool to size down the saves or at least "teach" its game to handle or better avoid such big sizes for the saves. That should have become obvious during the testingphase of the game before its release, because if you make such a big gameworld with so many possible ways to play the game, you should be aware of the possibility that some people actually play 400+ hours.
