Forge 1.12.2 crashing

[dom_ko]

I've been trying to fix this for like two hours and I've read other threads to try to fix it but nothing seems to make sense to me. Every time I run forge 1.12.2 it crashes. I tried removing a few mods here and there until I found one that seemed to change something. Now I actually get a crash report. I'm willing to post it if someone needs it.

@dom_ko First: How can you be helped if you do not show the crash report? Second: From what I know, version 1.12.2 is no longer supported.
