As of now, there is no Kernel Debug Kit (KDK) available for macOS 26.0 Developer Betas after the first build. Kernel Debug Kits are crucial for understanding panics and other bugs within custom Kernel Extensions. Without the KDK for the corresponding macOS version, tools like kmutil fail to recognize a KDK and certain functions are disabled. Additionally, as far as I am aware, a KDK for one build of macOS isn't able to be used on a differing build. Especially since this is a developer beta, where developers are updating their software to function with the latest versions of macOS, I'd expect a KDK to be available for more than one build.
No KDKs available for macOS 26.0 Developer Beta 2 and later
Have you filed a bug and, if so, what is the bug number?

As of now, there have been several additional KDK releases.
There is no KDK for macOS 14.7.8, and 14.8 either.
There is no KDK for macOS 14.7.8,
I wrote about this in this forum post, but KDK release are tied to XNU releases, NOT the system itself. In the case of macOS 14.7.8 it's the same release as macOS 14.7.7, which has a KDK. Both are running XNU 10063.141.1.705.2
and 14.8 either
This does appear to be missing. I'm looking into that.
