Thanks, I can confirm that it is fixed in 49.1.41.

Why? We use eclipse temurin to run tens of thousands of forge servers every day and the issue does not exist on any other forge version. Clearly there's something wrong with the launch script on that version. Have you tried running it yourself?

I am running the start script in the eclipse-temurin:17 docker image. It can run 49.1.36 without any issues.

That is the full output of the server. It does not create a log or crash report because it never gets that far.

When I create a completely fresh Forge server without any mods on 1.20.4 with Forge 49.1.37 it does not launch: https://paste.ee/p/g2K7a3T1

I'm trying to update the Mod Flywheel from 1.20.1 to 1.20.4 and get the following error message: java.lang.VerifyError: Bad type on operand stack Exception Details: Location: net/minecraft/client/Minecraft.handler$zzf000$flywheel$onEndManualResourceReload(ZLnet/minecraft/client/Minecraft$GameLoadCookie;Ljava/lang/Throwable;Lorg/spongepowered/asm/mixin/injection/callback/CallbackInfo;)V @20: invokevirtual Reason: Type 'com/jozufozu/flywheel/api/event/EndClientResourceReloadEvent' (current frame, stack[1]) is not assignable to 'net/minecraftforge/eventbus/api/Event' This error does not make sense as EndClientResourceReloadEvent extends net.minecraftforge.eventbus.api.Event. Does anyone know what's going on here? Full Logs: https://paste.ee/p/Ae28w Source code: https://github.com/JulianVennen/Flywheel
