It seems to be working fine.

Also please use something like gist.github.com for the logs. Pasting the text like this makes it rather hard to read and it seems the mod list is cut off.
As far as I can tell from the log, nothing points to Rechiseled.

Can you narrow down the mods need to reproduce the issue?

https://gist.github.com/MikelEFG/609c685c99267b34c3f84192a8c36205

I don't see anything pointing to the mod either but it's the only mod where if i delete it it immediately fixes the crash

Ah the error seems to occur in a config related class from Structure Gel.

that seemed to fix it, Thank you!
