Crash when trying to load minecraft Neoforge v 21.10.49, Minecraft v 1.12.10, Architectury API v 18.0.6

[Rumobok]

I have attached the crash report, as soon I click play on the launcher and it tries to load mods it crashes. I soon as this mod is removed I am able to load minecraft. I have also tried to just load just mod and I get the same issue.

Found that this API mod does work with NeoForge 21.10.34, I be using that version until the dev can up this API mod.

I am having the same issue. I think it broke on the 21.10.38 update for 1.21.10.

This happens with both 1.21.10 versions for me.

I'm also having this same issue. Some versions of Neoforge dont cause the crash, and others do. Architectury is the only mod I have installed as well.

Same Issue. I forked Architectury to see if I could hunt down where this was coming from.

The closest things I found that could possibly be messing with it seem to be:
MixinAbstractContainerScreen (I'm not entirely sure how it would be, I know that mixin is affecting the area causing it)
or somehow EventHandlerImplClient.eventContainerScreenEvent() but it seems to only mess with foreground? The error says

Caused by: java.lang.ClassNotFoundException: net.neoforged.neoforge.client.event.ContainerScreenEvent$Render$Background Which is confusing bc so far I can't seem to find anything in Architectury that even calls the .Render.Background method.

I hope any of this info is useful to you guys, I wish I was more help.

So is there an stable version that works on 1.21.10+?
