KB5046617 - Failed to Install repeatedly

I'm still facing problems trying to install the KB5046617 update on my Windows 11 machine. The installation repeatedly fails with the error code 0x800f0831 (CBS_E_STORE_CORRUPTION), which, from what I understand, points to corruption within the Component-Based Servicing (CBS) store.

This is what I've tried so far:

1. Running D*ISM Command: I executed the D*ISM clean-up image command to repair the image using a Windows ISO as the source: However, this resulted in another error: 0x800f081f, indicating that the source files couldn't be found:
2. In-Place Repair: I attempted an in-place repair of Windows 11 using the latest ISO, selecting the option to keep my personal files and apps. This did not resolve the update issue.
3. Resetting Windows Update Components: I followed the steps to reset the Windows Update components, including renaming the SoftwareDistribution and Catroot2 folders and restarting the necessary services. Despite this, the update still fails to install.
4. Using Windows Update Troubleshooter: I ran the Windows Update Troubleshooter, which identified some issues but wasn't able to fix the CBS store corruption.

Despite these efforts, the KB5046617 update remains stuck in a failed state. I'm unsure of the next steps to take at this point, other than perhaps a reset.
