Don't know how accurate it is but someone on another forum responded to me on the install issue with this:

"spoke with my insider friends at ms, anyone who did get the install successful is going to likely have audio issues and so on, this update was actually meant to branch into 26H1. They recommened uninstalling it and waiting a few days. The update is actually 4gb but only downloads the 700mb msu then fails to go to next step. Recommended DONT install"

Don't know how accurate it is but someone on another forum responded to me on the install issue with this:

"spoke with my insider friends at ms, anyone who did get the install successful is going to likely have audio issues and so on, this update was actually meant to branch into 26H1. They recommened uninstalling it and waiting a few days. The update is actually 4gb but only downloads the 700mb msu then fails to go to next step. Recommended DONT install"

The build notes were pulled, so that tracks.
