2 years ago I happen to have that KDK on my machine, so we can symbolicate your panic:

It looks like so->so_cfil is NULL at this point, causing the panic. Do you have any VPN or content filtering software installed? If so, try turning that off and trying again.
This is definitely a bug in the kernel, not one in unxip or even probably AirPlayXPCHelper. As such, I would strongly recommend filing a feedback with your steps to reproduce, including your coredump(s) and a list of your content filtering software, and probably a link to this bug as well. I'm definitely curious about what's going on here, and if I can mitigate it on my side while Apple fixes it, so you're free to send the coredumps over to me as well if you're comfortable doing so. But the best I can do for your kernel is perhaps find some more details about why the crash occurred, rather than being able to fix the underlying issue.

I'm trying to unxip Xcode_13.3.1.xip. It's my first time using unxip, but three times in a row I've had a panic 10–30 seconds into the process.
I'm on 12.4 Beta (21F5048e), maybe it's a bug with that given it's attributed to AirPlayXPCHelper. I'm not really familiar with panic logs as much as crash logs, I don't know where to start looking into this.
I have plenty of disk space, I'm unxip-ing from my ~/Downloads, I have a core dump I can send you somehow if that's useful.
