hey man,
I had this same problem but, a fix that simple, you need to downgrade to ElecCore-1.8.9-1.4.240 this version if keep crashing, seach in the mod folders to E-flux mod I removed E-flux and work perfectly, good luck and good plays to you.

Will be fixed, but this is not an ELecCore issue. I just need to recompile DR & EFlux
