This was fixed in today's patch
I know this isn't the same error code as you, but this is in the same area. it is a save error this is what i kept getting when trying to save the Sims 4 game. Sims 4 the game failed to save error code 510.70279b77:d2b7bb65, long story short i believe for now i have solved the problem hopefully it helps anyone else out. i tried everything making a copy of the file, deleting the file, repairing, and mean other things Google would take me to for fixing a save error specific problem to the game. finally at the end about fifteen minutes ago now i noticed that when i get the notification for the lifestyle brand i created for my Sim i could no longer save. i decided I've tried everything else so why not at this point. I went to my computer in the Sims 4 game and deleted the lifestyle brand and what do you know so far i can save the game again after all this time of testing everything on the Internet to fix the problem do what you would like with this information hope it helps someone else i know i really could have used this info about thirty hours ago.
This worked for me. Thank you so much!
