In the enigmatica 6 modpack version 0.4.0, fml.forgeVersion, 36.0.40, the log is getting spammed with config reload notifications, including:
[24Feb2021 21:11:06.482] [Thread-1/WARN] [net.minecraftforge.fml.config.ConfigFileTypeHandler/CONFIG]: Configuration file /Users/Rodger/Library/Application Support/gdlauncher_next/instances/E6 0.4/config/kleeslabs-common.toml is not correct. Correcting
See EnigmaticaModpacks/Enigmatica6#1396

It looks like Quark has fixed the issue here: VazkiiMods/Quark#3022
