CBS crashes on Windows 11 24H2 KB5046740
I'm trying to maintain a stable system, but every Windows update seems to trigger a CBS crash, making the machine barely functional. The issue first appeared after upgrading to 24H2, and despite performing several in-place upgrades (refresh installs), the problem hasn't gone away.
While the computer successfully merged all MSU files and installed the latest Windows version using the in-place upgrade process, I can't rely on this method for every update—it’s simply not practical.
Here’s what I discovered this time:
The Windows update KB5046740 was applied using an unexpanded variable, specifically referencing ($build.nttree). This occurred during the transition from version 10.0.26100.2314 (installed via in-place upgrade) to 10.0.26100.2454.
To fix the CBS crashes after the 24H2 update (KB5046740), try running the Windows Update Troubleshooter and clear the CBS cache by renaming the SoftwareDistribution and catroot2 folders.
Then, run sfc /scannow and DSM commands to repair any corrupted system files or Windows images. If the problem continues, check Event Viewer for detailed CBS error logs or manually install the update from the Microsoft Update Catalog. As a last resort, consider rolling back the update or performing a clean installation of Windows 11.

Have you tested ram and ssd are good and not corrupting windows? and your best bet is to do a full new fresh install of windows.
Note that the CBS thing is an INFO level message, which indicates it's basically just a breadcrumb and not a critical problem.
