Think it's pretty evident that much of it stems from the midfield. The current setup in midfield, where nobody has a defined role and it's completely fluid means our players need an extremely high awareness to be able to know who's staying back and who's going forward.
So far, the only player we've seen who can seamlessly go from defending to attacking is Arteta. Song has the ability but not the intelligence to do this; as we've seen in the past, his best defensive performances have come when he's given clear instructions to stay back.
The lack of a shield leaves our defense in too many one on one situations, and even the best defender will commit individual errors if left to hang so many times, hence the reason we concede from individual errors so much more often than others. Add our worst defensive injury situation in years, and tbh it's not entirely surprising.
