Crashing. This is what in logs:
[modloading-worker-12/ERROR] [net.minecraftforge.fml.javafmlmod.FMLModContainer/LOADING]: Failed to create mod instance. ModID: immersiveengineering, class blusunrize.immersiveengineering.ImmersiveEngineering
java.lang.IllegalArgumentException: Method public void blusunrize.immersiveengineering.common.world.IEWorldGen.chunkDataSave(net.minecraftforge.event.world.ChunkDataEvent$Save) has @SubscribeEvent annotation, but takes an argument that is not a subtype of the base type interface net.minecraftforge.fml.event.lifecycle.IModBusEvent: class net.minecraftforge.event.world.ChunkDataEvent$Save

What does it mean? Is it mod conflict or not?

With a terrible error report like this, I can't tell you.

I'd recommend downgrading to Forge version 88. If that doesn't work, file a proper report that doesn't completely ignore the issue template.
