im gonna be honest, i have currently 290 mods on Fabric, and the only information that I got from the crash report was this line at the beginning:

"at net.minecraft.class_3218.handler$oml001$ysns$addEntity(class_3218.java:29717)"

I will attach the full crash report, and also my personal configuration file. Thanks for developing this mod!
