Yeah I had the same issue, also with some other people (like the scavvers near the USS Constitution) turning immediately aggro. There's not a lot of info about this bug but it's definitely is a Bethesda Bug, not a FV bug.
If you're lucky, this is just because you have something on you with a targeting hud installed. Can be power armor, reg armor, helmets, modded gear, anything that works with targeting. It can apparently instantly make npc's see you as hostile. If you're lucky, simply reloading a save, un-equipping the armor in question and trying again will let you continue. (Companions with such armor also need to have it unequipped).
However, if you're not so lucky it could be that the bug isn't caused by armor. What's causing it then? Nobody knows. (Except maybe bethesda, but when have they ever been helpful with bugs). If this is the case, there is really no way to fix it, because no one knows where the problem is. Which is really shitty because, rare as it is, it has apparently been around since the beginning of the game, and Bethesda never bothered to even look for an answer.
I don't know if it will help, cause I haven't tried it myself yet, but logically, if you add yourself to an agressive npc's faction (or them to yours), it might prevent them from going hostile because they now see you as one of the boys.
14.AddToFaction <Faction ID> 1 is the command you'll want. You can replace 14 (14 is the player's id code so same as player.addto...) with an npc's code that shows up when you click them while in the console.
1 (at the end) will add them to the desired faction, 0 will remove them.Here's a list of all FO4 Factions:
https://fallout.fandom.com/wiki/Fallout_4_factionsIf you go this route, note that adding yourself to factions like raiders/gunners/super mutants/ etc will make all members of that faction friendly to you. Except maybe when you start killing them, but they won't be hostile on sight.
You could of course, add yourself to the faction, do what you need, and then remove yourself from the faction again.
Hope this helps!
EDIT!So 1; I'm one of the unlucky ones whose save is basically effed. But! it did give me the opportunity to test my theory, which brings me to #2
2) I was wrong, adding yourself/npc's to a faction does not help. I does prevent them from going hostile, but a quest will still fail.
e.g. Returning to Virgil with his serum, he and his bot & turrets were hostile for no reason. Adding myself to Virgil's faction did prevent them from going hostile, but upon reaching the point inside the cave where they always would attack me, I simply get the message "Failed: Give Virgil the serum", and despite him not being hostile, I still couldn't talk to him. So yeah, if the Targeting HUD isn't solving it, sorry mate, starting a new game will likely be your best option. There is no fix for this.
3) On a side note, I also made a mistake in my earlier explanation of the faction console command,
highlighted in red. Putting the value '0' at the end will add the target as just a friend to that faction. Adding '1' will add them as an ally.
To remove a target from a faction use the command TargetID.RemoveFromFaction <FactionID>
