I've had issues with crashes in a custom modpack and after removing mods until the crashing stopped, then readded the ones until I crashed again, I have found that ElecCore was causing issues with other mods. https://gist.github.com/skellitor301/1e1efff8fd97f22211d371bb94c2d1a2
this was on the 1.14.4 version of Minecraft, all mods are confirmed up to date for version 1.14.4, that was a potential issue brought up with IronChests showing 1.14.3 but that's not the case.
