Constant crashing with RAD

[breadooooo]

I play this as part of the Roguelike Adventures and Dungeons modpack and it has been crashing immediately every time I load in. The most recent error message is: crash-2021-04-05_09.52.18-server.txt

Level Up! Reloaded is the named issue every time

Same problem here. I've tried a lot to try and fix it, but so far nothing works. I don't know how to pinpoint the issue either.
