I have been able to temporary repair the system by manually deleting C:
\Users\eb\AppData\Local\MiKTeX and re-installing MikTeX from setup-5.3.1
+b8f430f-x64 (April 2023 according to file date). This old MikTeX works,
but an update then causes the same problem.

 
I never used the command line installer.
 
Yesterday I switched from my old MiKTeX 32 Bit to a new MiKTeX 64 Bit
version. I used the latest basic installer (January 28, 2024) and didn't
have any problems (on Windows 10). Also the updates could be installed.

The problem seems to be solved for the time being. I have done the
following:
- automatic loading of missing packages was set from 'ask' to 'yes',
that way the problem, should it re-occur, will not interrupt me in the
middle of a LaTeX run.
- After installing, I left the console without updating (ignoring its
protest) and did the first update on the command line. Further updates
and package installs are then possible from the console.

Nevertheless, this seems to be a frequently re-occuring problem that
should be looked into. Unfortunately, my programming skilles (or the
lack of them) don't allow me to do so myself.
