EPIC Launcher rework needed!

I installed the devkit through the epic launcher, which downloaded v200.5. I tested cooking the DinoArena mod, which crashed at run-time during loading in SinglePlayer on the v204.1 client on Steam. I downloaded the new 201.6 devkit binaries from github, and DinoArena still crashes on load for Steam. Are there tightly-coupled dependencies that modders need to be aware of in order to make mods run in the client? I’ve been attempting to get a simple mod to run without success.
