Guys,

I tried everything what I found on the internet, used cmd with comands for sfc scannow, restore health, reset WU, delete software distribution subfolders, downloaded manually and nothing. Anyone know what should I do to install this update?
All other updates are installing normally exept this one.

Windows 11 Pro Licended
ryzen 7 7700x
32Gb ram 4x8gb ddr5 6000mhz

that error code means some update files are missing
try those command in windows terminal:
dism /online /cleanup-image /restorehealth
sfc /scannow

then run windows update troubleshooter

if that doesnt help, try installing that KB package manualy, you can download it from here
