OK, so you didn't update MiKTeX manually.
I don't know if Miktex was really broken, but LyX was no more able to
launch the compilation of the documents. Then, as I wrote you, a Miktex
update failed and it is only later that on the Miktex console I have
seen that there was proposed a list of packages to be installed with one
package inside. After the installation of this package LyX (2.2.3 and
2.3) were both able to compile again documents.
Presently all seems to work fine.
OK, then the problem I detected yesterday seem to exist since Monday on
some mirror servers (I'll check right now if this is now fixed and
report back). MiKTeX must be updated to be able to work with it, but the
update failed because the main package containing the info of all other
MiKTeX packages appeared recently truncated on the MiKTeX mirror servers.
Since you had a state of MiKTeX with the new MiKTeX console, it means
that the update was partially successful. When I launch in this state
the MiKTeX console manually and force another update run, I get MiKTeX
fixed. And this is what you did too.
So my analysis is that the LyX installer could force the update to the
MiKTeX console but the packages and, more important, the links to the
packages could not be updated by the MiKTeX console because of the
truncated package info.
In my opinion you should concentrate on the reason of the presence in
bundle3 of this dialog window with only an "OK button" to click as
possible answer as we should be in position to decline the proposition
to update Miktex
In this case we must force an update. You observed what happens if this
is not performed or incomplete - MiKTeX can be broken.
The MiKTeX package handling changed and the different programs to
install and maintain packages do no longer exist. They were replaced by
the MiKTeX Console. Therefore we must find a way that users of older
MiKTeX get the console because if they do this by themselves (e.g. by
installing a new package or in same cases by reconfiguring LyX) a bug in
MiKTeX can cause LaTeX to break completely.
many thanks for your help with testing and feedback
