ADDITIONAL INFORMATION
* Note I was having this issue on 22.04.3 and noticed newer versions on the bug
report, so I upgraded just ark to 22.08.0 . So if the versions don't match up
that might be why.
Using GDB I noticed every time I interrupted the program it seemed to be stuck
in:

/usr/lib/libQt5Widgets.so.5
Here is one back trace.

I can open the attachment in Ark in an external browser.
I did see bug 454181 but the symptoms were different.
