I had the same problem in 1.12 my game would not launch and stayed in the task manager. In fact if you remove konkrete + fancymenu it should work again.

Oh same thing just happened to me. Very unfortunate incompatibility.

Thanks to this issue, i was able to confirm it's a mod bug :) (sadly) While i do hope this bug get's fixed someday, this is what you need to do to fix it, and keep the rest:

# Set this to false to disable the Minecraft class patches (the Toggle Narrator keybind and custom window title/icon).
# Default: true
B:patchMinecraftClass=false

by disabeling this, it won't patch the classes it conflicts, thus making it all work again :)
