Hi @littlewu2508, sorry for the delayed response.
If you're still interesting in figuring this one out, would you mind sharing a PDF that could help to reproduce this issue? I've just compiled my fork and all the PDF files that I tested were opened just fine (although I have to admit they were rather simple 1-5 pages files).
Having said that, this project hasn't received much love in a while, so it's more than likely that it might need to be reworked in some places, particularly with the migration from KF5 to KF6.

Try this document:
https://ftp.jaist.ac.jp/pub/CTAN/macros/latex/contrib/lipsum/lipsum.pdf
The only pdf I can open without crash is a some text generated by the following tex file:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\begin{document}
\lipsum[1-100][1-100]
\end{document}from okular-backend-mupdf.

Thank you for providing the sample file, I was able to reproduce this on my end.
I'll try to spin out a clean testing environment to further investigate on this. Attaching my trace.
