Forge 1.12 crashing

[alexniem]

I am posting this a second time as my last post got removed since 1.12 isn't supported on the forums. Although, I still require an answer as the mod I am trying to use (Schematica) only works in 1.12. The query is below

Yesterday I installed Forge 1.12 and it worked perfectly fine. Today I tried to launch it and the Minecraft launcher crashes. I don’t know what the issue might be. Here is the latest log that I could find.
