I can't play my game!

I have managed to get my game running again. This is what I did: 

1. took the saves-folder out of my Sims 4 folder in Documents and put it on my desktop
2. also moved my Mods-folder to my desktop
3. started the game and turned on script and custom mods
4. moved my mods from the folder on my desktop back into the newly created mods-folder in Documents (I didn't copied the folder, but only the mod files)
5. started the game again and created a new random household and let it move into a house
6. save the household and then close the game
7. copied my old save files into the newly created save folder (there should also be the brand new save file from the savegame you just created)
8. started the game again and it actually loaded all save-games without crashing

I have not yet tested whether the game crashes again if I continue playing my main save file, save and then load the game again. But at least i could get it running again. Will probably wait for an official bug-fix. Just to be safe.
