Update error (0x80073712)

Hello everyone, I just want to ask for your help regarding the Error code: (0x80073712). I cannot update my laptop because of this.

My current OS build is 17134.407
Version: 1803
OS: Windows 10 Pro
Model: Lenovo T480


I just do not know why it won't update. It keeps saying that some update files are missing. The update it is currently trying to install is KB4503286. I tried manually installing updates, even earlier ones, by downloading from microsoft's website but that method won't work too. My firewall is already turned off when trying to update.

Any help would be appreciated. Thank you.

Unfortunately, that one did not work. I am still getting the same error.

1) perform a reset save files or reset save files equivalent (reinstall drivers and applications)

3) troubleshoot the failed upgrade

4) If you prefer option #3 then perform the following steps:
