The HomeKit component disappears after the initial setup procedure to identify the devices.
Starting from scratch by removing the .homekit.state file, HA provide a PIN as expected.
On my iOS device I open the Home app, add the accessory manually (like I’ve done many times before), insert the PIN provided and go through next, next, next to ident all the devices.
The Home app is also open on my Mac. It starts showing the devices as I go through the setup, albeit with a ‘No Response’ on each item.
All devices are ‘No Response’ and after a random time disappear.
I’m on Hassio 0.98.5
