Process Protection Failures after LiveUpdate Occasionally. Why?
It could be that your system just needs to be restarted to fix some outstanding issue. Be sure you are using the Restart command. Not Shutdown and startup again if you have Windows Fast Startup feature enabled. If you use Windows 8/8.1, 10 or 11, there can be an issue with the Windows Fast Startup feature.. See more information here.
Also, during a LiveUpdate it is always possible that something went wrong with the download. Running LiveUpdate again should re download the failed module.
