Imo there's a good chance that
https://invent.kde.org/graphics/okular/-/merge_requests/291 fixes both "text no
longer selected" and "crash".

Currently TextSelectorEngine holds a raw pointer to a PageViewItem owned by
PageViewPrivate much longer than intended. Some unrelated PageView interaction
can delete that PageViewItem in the meantime, leaving
TextSelectorEngine::m_lockedItem dangling and causing crash on next access to
m_lockedItem in TextSelectorEngine::event.

The attached crash dump is in line with that guess, so it may be worth trying
MR 291.
