It's only one core pegged at 100%, practically nothing else, which means it's a sequential workload entirely blocked on defender.

Oh, you mean that Defender locks your thread?

I don't recall seeing significant locking in the stack samples, just that the scanning happens synchronously during some IO (e.g. closing file handles) and >90% of the CPU cycles are spent on defender. Which effectively boils down to a task that should be IO-bound becoming bottlenecked by waiting on defender.
