Steps to Reproduce the Crash

Crash occurs only with JEI + Evolved Mekanism – Removing any other mod (e.g., Terralith, Macaw’s Doors, Quark, Serene Seasons) sometimes prevents the crash, but only removing JEI or Evolved Mekanism guarantees stability.

Mod count is irrelevant – Even with 300+ mods, the game runs fine as long as Evolved Mekanism is absent.

REI works as an alternative – Replacing JEI with REI does not cause the crash, confirming the issue is specific to JEI's interaction with Evolved Mekanism.
