On a dedicated server it looks like running EvilCraft and Malum together causes a crash if the Vengeance Ring from evilcraft is enabled. To reproduce the crash, enable the vengeance ring in evilcraft, equip it to a curio slot, and kill any mob to spawn a vengeance spirit. It should crash soon after (you may have to swing at the vengeance spirit itself).

sammy told me to tell you this has been fixed in the indev versions (https://github.com/SammySemicolon/Malum-Mod/tree/1.18.1-dev)

The indev-version that fixes this issue for you can be downloaded from here: https://www.mediafire.com/file/svh32z7jfiehw6z/malum-1.18.1-1.3.jar/file

A few more features are yet to be added before this is the official release of 1.3.

As a note; this happens when malum damage calculations happen on some modded entities, not sure why or how and I can't reproduce it. Regardless, it'll be fixed in 1.3 as isNaN and rttv stated
