Hello there,
Some points you can try to sort this issue are listed below, try each one of them to see if they are helpful to you.
-Are there other anti-virus programs installed in your environment? Try adjusting or disabling the relevant supervision function to complete the update installation.
-Look into the WindowsUpdate.log to see which file and which hash doesn't work.
-If you are using WSUS to approve updates for the client, confirm your WSUS system version.
I would first suggest you try getting the updates manually and see if you can install them.
You can get the updates by KB (KB5016623 ) number from the below link
https://www.catalog.update.microsoft.com/Home.aspx
You can also temporarily disable all your antivirus and try installing the updates.
If this manual update fails you can then try using the SFC & DISM command to check for any corrupted registries and try the update installation after the restart.
