Hello.

I'm trying to install Flywheel with Create on Minecraft 1.18.1 on macOS M1
The reason I use custom launcher is because it supports custom java and this java is optimised for ARM (M1)
But every time I launch with Forge 39.0.0 and Flywheel 0.4.2-rc it crashes, but on mojang's launcher it doesn't. I want to use custom launcher cuz it doesn't have such performance and energy impact as original.

Here's log

Launcher: MultiMC, java zulu-17, installed via this tutorial https://www.youtube.com/watch?v=bb-laqqlHWg

Sorry to hear, but this is the wrong place. I can't help you, but it looks to me like the launcher isn't correctly loading lwjgl. Can you even run an unmodded instance through it?
