Accidentally typed the minecraft version twice, sorry!
Forge version is (if i'm reading it correctly): 14.23.5.2860.

Two options,

1. try https://www.curseforge.com/minecraft/mc-mods/universal-tweaks - it adds various fixes and might solve this for you if the issue is locale-dependent
2. if it didn't help, there is a config option to disable loading of the Wizard's Handbook (ebwizadry manual), I can provide you a .cfg file in the discord server if the file didn't generate

I have the same problem too
