Hi! I have a problem with immersive engeenering. So I want to update the mod to the latest version, but then I also must update a forge. When I updated forge to the newer version it crashed.
I use forge version 1.12.2-14.23.5.2768.

This is my crash log:

Ok thank you, so what I should do to fix it?
Sorry for this wall of the text I'm new.

np, check if you got the mod called obfuscated installed and try to update it

Ok, I did it but it still not working

please use pastebin and do not post a wall of text

also this looks like a crash from the Obfuscate Mod (at least it cites the same lines and stuff as in the Obfuscate Issue)

You'll need to provide the full log, on pastebin, to get any help.
