See original GitHub issue

Issue description

While prepping a release for my modpack Rotten Economy I updated to the just released 1.12.2 version CraftTweaker2-1.12- and could no longer start minecraft as it crashes almost immediately with a stack trace pointing towards CraftTweaker.

Stack Trace Snippet

The full trace is in the attached gist link but here is a quick peek:
