Yes, about four years ago I set bidi-display-reordering nil in my Emacs
init files. Now it seems to me that I used a wrong variable for what I
wanted to do. I should have set bidi-paragraph-direction left-to-right
which I did now.
It looks like Emacs is not crashing anymore so this was all my mistake.
Thanks for mentioning bidi-display-reordering. I'm closing this bug.

Emacs daemon crashes when scrolling through a buffer. I believe it
happens when buffer is trying to display Arabic letters that are in my
mail summary buffer. I used "git bisect" and found that this is the
first "bad" commit:
commit 30a7ee505aca3cc285699bae1630a28185519d99
Author: Eli Zaretskii <eliz <at> gnu.org>

Fix Arabic shaping when eww/shr fill the text to be rendered
* src/hbfont.c (hbfont_shape): Don't use DIRECTION if the current
buffer has bidi reordering disabled. (Bug#41005)
My Emacs daemon process is managed by systemd and the logs have this
backtrace:
