https://discuss.kde.org/t/plasma6-discover-crashed-when-startup-in-simplified-chinese-locale/11337 suggests this happens only when the locale is set to chinese, but even with that I can't reproduce

Comment 4 4sfvnla7 2024-03-20 14:59:36 UTC 
I think I have encountered the same bug (ASSERT: "isSorted(cats)" in file ./libdiscover/Category/Category.cpp, line 240). Some of my observations:

1) the KDE neon was installed in Simplified Chinese. At this moment Discover could be opened normally (if I correctly recall).
2) after at most one day (with many things like update packages, install nvidia driver, etc.), Discover started to crash with the error above. At this moment I could circumvent it with LC_ALL=en_US.utf8.
3) after several days, the workaround in 2) stopped working (crash with the same error). I can still circumvent it with LC_ALL=POSIX or LC_ALL=C (C.utf8 or ja_JP.utf8 crash with the same error); the workaround does not affect display of CJK characters in Discover. I installed Japanese as 2nd language in system settings in the meantime; idk if that's relevant.

KDE neon 6.0, Plasma 6.0.2, Framework 6.0.0, Qt 6.6.2, Linux 6.5.0-25-generic x86-64, wayland.

Comment 6 Harald Sitter 2024-05-06 10:31:15 UTC 
I find it suspicious that this only happens on neon.

Sentry trace also only has neon https://crash-reports.kde.org/organizations/kde/issues/3676
Comment 7 Harald Sitter 2024-05-06 12:53:07 UTC 
Found the problem. The hints about only some languages being affected was incredibly helpful!

What happens is that some languages have ambiguous translations of category names 

e.g.

msgctxt "Category"
msgid "Simulation"
msgstr "模拟"

vs.

msgctxt "Category"
msgid "Emulators"
msgstr "模拟"

which then trips up implicit uniqueness requirements we have in our assertions. It also plain makes no sense to have the same translation used for different categories. They need to be disambiguated one way or another or the user won't be able to differentiate what they are.

The reason only neon is affected is probably because it builds with assertions on.
