Thanks. To me it tells that you have Okular 20.04.x (1.10.x) installed, but not
the package okular-dbgsym. Can you install that package and wait for the next
crash, or did you already try that?

The problem (as I read it) is somewhere in PageView::*Event(). We can read that
it is something with event handlers and QScroller, probably QScroller got an
invalid pointer somewhere. All the ??? make it difficult.

Do you remember whether Okular crashed when you tried to scroll, or did it
crash immediately at opening the file?

QScreen is also involved. Unlikely, but possibly a reason why it crashes only
on your system?. Do you have an uncommon screen arrangement? (Diagonal,
negative DPI, whateverdontknow... ;) )
