Update:
I took SomeOtherGuy’s tack and this company has graciously (no sarcasm here) agreed to do an exchange for the bolt.
Thank you all for your thoughts and direction.

Does the new bolt hand cycle in your bc ok? Hold the bcg in your hand and cycle it...any probs?
Sounds like the locking lugs on the bolt are too large front to back or less likely too thick side to side. If you have some calipers you could check.
Have you checked if the firing pin can move freely in the bolt ? I just a very short similar situation and it appears my bolt was a little tighter which prevented the firing pin from moving freely which prevented the lugs from unlocking .

did you use the old cam pin?
I had a problem like this, and i ended up comparing cam pins with my stash, found that the "incumbent" cam pin was maybe a couple thousandths smaller dia, so I put in one that was a little bigger (thousandths). that worked.
however. it seems that the bolt isn't fully rotating to the unlocked position. that's why the bigger cam pin helped, because then the bolt rotation tracked the cam slot better. could also be that the old cam pin was slightly worn.
could also be this suggestion is nonsense in your context. FWIW.
