pdflatex fails after recent update

[LaTeX1729]

After the recent update pdflatex fails. here is what I believe is the relevant portion of pdflatex.log.

Hello
I confirm that issue.
If I compile (with pdflatex):

\documentclass{article}
\begin{document}
Hello
\end{document}

no problem.

But if I compile:

\documentclass{article}
\usepackage{bera}
\begin{document}
Hello
\end{document}

the log is:

[test.log](https://github.com/MiKTeX/miktex/files/4844447/test.log)

and, in pdflatex.log, I have:

Same here - urgent problem! Paper deadline near ...

[edocevoli]

Just to note: lualatex and xelatex are not affected by the bug.

[edocevoli]

A bug fix will be rolled out with the next update.

If you need the fix now, you can download this Zip archive

http://download.miktex.org/tmp/93068FDE-AB9D-4B89-AE78-F44BEC9C59F2/568.zip

and drop the file miktex-pdftex.exe into the MiKTeX bin directory. You then have to create the pdflatex executable by running initexmf --mklinks --force (add option --admin if this is a shared installation).

[petiard]

It works!
Thank you very much for your quick response!

Same problem here and transferred to the online platform.

You have installed the executable? If yes, then running pdflatex --version outputs this banner:

MiKTeX-pdfTeX 4.0.1 (MiKTeX 20.6)

[bartbv]

Thank you for your fast reply! Running the .exe did the job.

[edocevoli]

This has been fixed.
