Try disabling all the modules and see if you’re able to install KB5016629.

Uninstall Malwarebytes

If that doesn’t work out, you need to uninstall Malwarebytes from Apps & Features (or Programs and Features) so that Malwarebytes kernel drivers and Service(s) don’t load with Windows. Only if necessary, you need to use the Malwarebytes Support Tool (in addition) to do a clean uninstall of Malwarebytes Premium.

Turn off Windows Defender Real-time protection

Additionally, you may turn off Microsoft Defender Antivirus real-time protection.

(Some users have indicated that they had to repair Windows Update and clear the WU caches in addition to the above steps.)

Once you successfully install the KB5016629 Cumulative Update, you can reinstall or turn on the real-time protection in Malwarebytes and Microsoft Defender.
