Windows 10 crashes when installing Update KB5120249

Whenever windows update attempts to install update KB5120249, it freezes during the configuring updates stage and I have to perform a system restore each time.

I have tried multiple times to stop it from installing it, including using the show/hide updates tool but it always tries to install after a reboot.

    Thanks, Rob. The Build is pretty old as I see.

    Will need to dig further.

    To better understand the issue, Please see the article below on how to share System logs.
