1st of all, it's a fantastic, Isekai anime, not total new, not not too old, may be aired in last 3 years or so.

The scene is of a wraith (spectre) attack a carrage with the mc and his father in it. And only the mc is able to see it but his father was able to see due to presence of a magical lamp in the carrage.

Hope it helps and you can narrow it down. Thanks.
