SSU output is attached. Installation fails for Intel Dual Band Wireless-AC 8265. Windows Update had attempted to install and failed, rendering the wireless adapter unusable. Subsequent attempts to repair the installation manually, including by installing WiFi_21.80.2_Driver64_Win10.exe directly as well as using the automated tool, were unsuccessful with the message "A fatal error occurred during installation".
SSU output is attached and key section excerpted below.
Driver I attempted to install both automatically and manually:
