#130
Yep--something in your present build (possibly a device driver--GPU driver, etc.) is throwing up a roadblock to the build install, and so the system automatically reverts you back to the previous build. I've seen it a few times myself over the years. No point in repeating the process as the outcome will not change--unless you can figure out what is obstructing the upgrade and fix it while you are running 18323. Barring that, just wait for the next build.
