Visible crew/equipment: Indy is at the nuclear test site and exits the house and comes out front. He knocks over the boy on the bike and air raid siren goes off. Just as he stands upright, in the window with curtains, you can see a reflection of a crew member walking by.
Suggested correction: I'm watching the Disney+ copy frame by frame, and there's no reflection anywhere.

Actually, the mistake is correct. The crew member's reflection is at 00:19:32, reflected on the right curtain over Indy's right shoulder, next to the fake boy inside the house.
