Tried several times to install the latest 22H2 update, KB5021233. Apparently no trouble downloading and doing preliminary install. Then, after first restart, fails at 97%. After recovery and restart, Update panel shows it failed with 0x800f0922.
My system: Asrock Z370 Pro 4.
Pre-install: firewall and vpn disabled.
SFC showed no errors.
DISM CheckHealth and ScanHealth showed no errors.
