Null Pointer Exception at startup

Hey, I understand this may not be an Iris issue, but I'm not a shader guy so any help to narrow it down is much appreciated. Here's the error that appears on client startup:

True to its promise, joining a server shows no shaders, just vanilla graphics. I'm running on macOS, with the latest Distant Horizons mod for Fabric.
