Anyone else having issues installing this update? My 2018 mini has been hit or miss when it has come to installing updates since Big Sur. Normally when it fails thru System Preferences I could get the update to run by using softwareupdate -i -a in the Terminal, but now I am getting:
Failed to download & prepare update: Error Domain=SUMacControllerError Code=7723 "[SUMacControllerErrorPreflightPersonalizeFailed=7723] Failed to perform PreflightPersonalize operation: [MobileSoftwareUpdateErrorDomain(MSU):MSU_ERR_PACKAGE_FAILURE(29)_1_MobileSoftwareUpdateErrorDomain(MSU):MSU_ERR_INTERNAL_ERROR(7)]" UserInfo={NSUnderlyingError=0x7f8915e04a20 {Error Domain=MobileSoftwareUpdateErrorDomain Code=29 "Failed to verify package contents."

I had this trouble with 11.3.1 as well, but the full installer InstallAssistant.pkg worked. Unfortunately nothing is working this time.
