Win Defender KB4052623 (v4.18.1905.4) repeated install fail 0x80070643

Can someone please tell me more about this situation? This Windows Defender update is repeatedly failing to install: KB4052623 (Version 4.18.1905.4) installation fail with Error 0x80070643. I have searched various forums for a solution, but have found none so far that pertains to this specific version.

Also, when I try to manually update Windows Defender from within Windows Defender, I get another error message saying: error code -2147023293 protection definition update failed.

Thanks in advance for any help provided. I should add that I have no 3rd party AV installed.

Here are the respective screenshots of the error messages:

What I am suppose to do? Is it OK if I do nothing further or I got to re-install KB4052623 if, so then how?

Your valuable suggestion is needed.

Thank you in advance.
