"Think this is the same problem Yep Error 0x80070643 again!!!"

Not so.

(0x80070643) indicates something cannot be installed, not why.

The something, in this case KB5001716 (S), is the problem. Win 10 64 bit refuses to install it. It installed KB5001716 the previous day, and it installed other updates the same day, which would indicate KB5001716 (S) is faulty, not that the update software is faulty.

With this update in particular more users are reporting the same issue if it has been previously installed, you can try to delete the previously installed version and it should proceed:
