I'm using the 2.3.0 version of replay mod for Minecraft 1.14.4, my game won't launch because "Could not execute entrypoint stage 'client' due to errors, provided by 'replaymod'!".
I expected the game to launch.

This is a duplicate of #162
In the meantime, you can either use ReplayMod 2.2.0-b7 or remove Optifine.
