Setting the clock does not count as synchronizing it. The Pi-specific GUI insists that NTP must be working before it will allow update.Try syncing the date manually sudo date --set '2024-08-03 09:25' then it should stay sync'd.
(It also tries forcibly restarting your NTP client—I do not know if there are any situations where that would help. And it believe its use of timedatectl can end up starting systemd-timesyncd in competition with the daemon you were running.)
However, as long as the clock is roughly correct, sudo apt update && sudo apt full-upgrade should be fine.
