I reinstalled okular as you suggested but did not solve the issue.
Yes, it can open other pdf file. The issue seems to be with this file. While manjaro has no issue even with this file. And MasterPDFEditor can open this file without any issue.
Here is the journal log/

Edit: The issue seems to be with digitally singed pdf from packages other than okular. While okular in manjaro has no issues and masterpdfeditor works fine as well, Okular in EOS is crashing. The okular version is same in both linux. The issue happens even with latest LTS kernel in EOS only.
Perhaps Manjaro, due to its release cycle, has an older version of poppler.
I am not seeing any recent bug reports about this, but perhaps you are simply the first person to discover it.
I think you might have trouble downgrading poppler due to dependency issues, but you could try downgrading okular to a previous version and see if that works.
Yep, Manjaro is at poppler 23.03.0-1 while your EOS has poppler 23.05.0-1. This might be why opening digitally signed documents works in Manjaro but not for you in EndeavourOS.
You can try downgrading poppler; you’ll probably have to downgrade a couple of other packages as well in order to do it. Pacman will inform you if there are any packages preventing the downgrade; if the situation isn’t too bad we can give it a try.
I am on the latest Okular (23.04.1-1, from 10th May) and Poppler (23.05.0-1, from 13th May) packages and I haven’t yet encountered a PDF that causes Okular to crash.
