I read that this update was supposed to be optional but mine installed anyway. First of all my laptop became very unresponsive and took ages to open programs and browsing became very slow. In the end I uninstalled it. A day or so later I got a notification that it was ready for installation again. I thought you may have fixed the problem so installed it once more.
This time round I got a great deal of lag and my HP support assistant warned me that I had no firewall protection or anti virus installed. I was unable to open defender as it appeared not to be there. Neither could I open Malwarebytes.
I have now uninstalled KB4541335 and firewall etc are working once more. Have paused update installation for 14 days and hopefully you may have found a fix by then.
