Minecraft 1.18 Forge MDK, almost no changes from example

Data Generator fails with MouseTweaks:

[04:41:40] [modloading-worker-0/ERROR] [ne.mi.fm.ja.FMLModContainer/LOADING]: Failed to create mod instance. ModID: mousetweaks, class yalter.mousetweaks.forge.MouseTweaksForge
Caused by: java.lang.NullPointerException: Cannot read field "gameDirectory" because "yalter.mousetweaks.Main.mc" is null
    at yalter.mousetweaks.Main.initialize(Main.java:46) ~[mousetweaks-60089-3578801_mapped_parchment_2022.11.06-1.18.2.jar%2392!/:2.21] {re:classloading}

Is it the intended behaviour? How to skip client-side mods on dataGen?
My gradle:
runtimeOnly fg.deobf("curse.maven:mousetweaks-60089:3578801")

Everything works fine on runClient task but I can't generate data

Seems like Minecraft.getInstance() should be null-checked on Main::initialize because its null on datagen

Is there any way to skip loading MouseTweaks completely on runData task while its not fixed?

Hey, so uh, I've no idea how the data generator works, I've never used it. If you find a way to disable Mouse Tweaks when running the data generator, could you please submit a pull request?

Yeah I'll do what I can a little later tonight

Sorry still a bit busy, Im still here and gonna deal with it asap

Thanks and no rush
