Please read the FAQ (orange banner at top of page), and post full logs as described there using an external site such as https://mclo.gs It is very possible there is information in the log that could point to the problem, that is why posting the entire log and not 1 line is most useful.

Why Has the Forge Development Forum Become So Empty?

I agree, and that's why I've enabled the RSS notifications for the forums on my phone. Often times it is difficult to share things on here that can be condensed into a single forum post. As for development, the discussion that happens on GitHub is not for releases but rather for the active development of the feature itself. I'm happy to discuss more things on the forums in the future, but I've been more focused on keeping my head down and getting things working. There's still a lot to do with the toolchain before I can do more things on the forums and the Forge project itself.

I need a mod to help build something similar litematica

Try Structurize or Building Gadgets — they work great on Forge 1.20.1 and are probably the closest alternatives to Litematica.

Yeah, you’re totally right — it’s been noticeably quieter here over the past few years. Most of the modding discussion has definitely shifted to Discord servers and sometimes Reddit, since they offer faster responses and real-time collaboration.
Forums like this used to be the main hub for documentation and troubleshooting, but now people prefer quick chats or sharing snippets on GitHub and Discord. The downside is that a lot of useful info gets buried or lost over time instead of being archived like it was here.

java.util.ConcurrentModificationException: null - Exception in server tick loop

Use Java 17 instead of Java 21
