@ZOS_MikaS you might want to reconsider where you moved this thread to. Since OP is talking about "patch 1.35", which would be PS4, the PC Technical Support forum may be a slightly awkward location...
OP, sorry, can't help you since I actually am on PC...
If you are still getting this error when running the update, please try deleting the download followed by restarting your PS4. After the restart, try starting the update again.
