--- Comment #16 from Regina Henschel <rb.henschel at t-online.de> ---
Your images show, that it is a problem with fallback for missing glyphs. The
rectangle which can be seen in "Math noto serif" is the indicator for a missing
glyph. And indeed, font "Noto serif" does not contain the needed subset "Basic
Arabic". Fonts "Noto Naskh Arabic" and "Tahoma" contain this subset.

I have no idea, why glyph fallback does not work on your system but works on my
system. But you can use a workaround: Format > Fonts in Math has a button
"Default". This puts the settings to your user profile, so that all new
formulas will use them. So you need to find a font, which has the needed subset
and set this font in Format > Fonts. Then click button "Default".

If you have already got "Segoe UI" that might work. It is a more recent font
than "Tahoma" or "Times New Roman".
You can add additional fonts and language support to Windows 10 from Settings >
Apps > Apps & features > Optional features > Add.

I put the bug back to "Unconfirmed". Unfortunately nothing can be further done
until someone can confirm the problem.
