Good morning, Seems the BOAR have an audio file issue at distance. Clip included you can catch the audio as I approach. After killing it with a crossbow, carbon bolt then glitched, creating a 5/5 stack that could not be interacted (You can see I attempt to hand, to stack)

Approach BOAR from 200M to catch the audio file issue, Use crossbow with carbon bolt and kill, this should duplicate the issue.

Correct Audio and Allow retrieval of item.
