Welcome to the Forum!
it's highly possible that a cleaning may be in order. Now,, since it's new to you,, & to prevent major frustration,, just get a can of spray brake or carb cleaner,,. Then,,, open the bolt, spray some inside,,, work the bolt,, a lot,, while "flushing out the innerds!" After that,, a few drops of oil internally, (don't overdo it,) working the oil in by cycling the action, try shooting it again.
It's very possible that there is some packing grease slowing down the firing pin,, or the bolt isn't getting fully seated. Quite often a new gun has grease or a small piece of whatever that causes minor hic-cups like this.
Just one possible reason.
Shoot straight and safe!
