What 'fix patch' are you talking about?
They're referring to the Unofficial Patch, which is run by the incredibly dedicated Unofficial Patch team (Arthmoor and others) to fix all of the bugs plaguing the game because Bethesda doesn't care about fixing 99% of the bugs in their games. It's gotten to the point that Unofficial Patches have become essential to a bug free experience.
They also have one for Fallout 4 and I believe there'll be one for Starfield too eventually.
