xelatex crashes if fonts are called by name and the open type renderer is used

[u-fischer]

Since todays update (which updated quite a lot binaries) the following crashes for me if I compile with xelatex.

\documentclass{article}

\begin{document}
\font\blub="Arial/OT" \blub  %crashes

Hello World!
\end{document}

A similar plain tex document crashes too with xetex

\font\blub="Arial/OT" \blub  %crashes

Hello World!

\bye

The log-file is empty. It works fine if one remove the /OT and use only \font\blub="Arial" \blub.

I deleted the font config cache and recreate it but this didn't resolve the problem.
The problem has also been reported here https://tex.stackexchange.com/q/625342/2388

Thank, I am able to reproduce/debug it. Seems to be a Windows-specific issue.

This has been fixed.
