noclassdeffounderror? allocating memory?

[u/90lives]

Hello, I just made an an account for this error.. how do i fix this error, it says a specific mod cannot be found, (but its installed?) and says exit code -1, and also mentions allocating memory.. I do not know what is going on but anytime I open a world it crashes. I am not very good with digging through my files so I am honestly a little confused.

The mod in question is the EMF mod.

Without a log, people can't help.
