Preston Garvey gets aggro (Fallout 4)

at the beginning of the game, as I arrived in Senchuari with the settlers, I accidentally shot at Preston Garvey.
Now I can’t turn in the quest to him, he always attacks me.
At first, I decided that it would pass by itself, and completed 3-4 other quests. There are no saves before the incident,
but there is no desire to replay everything.
Has anyone encountered this?
how to pacify an NPC?
