Error 0x8007045d on windows 10

My windows 10 update cannot proceed for unknown reasons. I have also tried using the automatic updater in the microsoft website but it did not solve my issue either. Does anyone have any idea what is causing this error? Thank you.

Run the SetupDiag to check where is the problem with the update.
1-Download SetupDiag.
https://go.microsoft.com/fwlink/?linkid=870142
2-If your web browser asks what to do with the file, choose Save. By default, the file will be saved to your Downloads folder. You can also save it to a different location if desired by using Save As.
3-When SetupDiag has finished downloading, open the folder where you downloaded the file. By default, this is your Downloads folder, which is displayed in File Explorer under Quick access in the left navigation pane.
4-Double-click the SetupDiag file to run it. Click Yes if you are asked to approve running the program.
5-A command window will open while SetupDiag diagnoses your computer. Wait for this to finish.
6-When SetupDiag finishes, two files will be created in the same folder where you double-clicked SetupDiag. One is a configuration file, the other is a log file.
7-Attach the file SetupDiagResults.log.
