Cumulative update KB5001391 fails to Install

Ever since KB5000842 printing has not worked correctly for us especially when printing PDFs, with KB5001330 breaking Microsoft's own 'Microsoft Print to PDF' and a ton of HP printer drivers resulting in 0x800f0922 error if you try to reinstall them. Only solutions we've found if you are already on Windows 20H2/2004 with all updates installed is to uninstall KB5001391, reboot, uninstall KB5001330 (not visible unless you remove KB5001391 first), reboot, remove 'Microsoft Print to PDF' from program and features/turn features on and off, then add it again (the print spooler is now working correct), install KB5001649 (to fix PDF's missing headings and logos caused by KB5000842), then hide update KB5001330 to prevent it from being installed by Windows Update again. Whilst this does not get KB5001330 and KB5001391 installed, it did at least get our printing services running again, so might help others.
