For sharing code, I would suggest putting your mod on github, it would allow someone to build/run your mod to help test, as well as peruse the code. I would at the very least share the code for your new material/tool tier, my first thought would be that it is related to the enchantability level of the material.

Please read the FAQ (https://forums.minecraftforge.net/topic/125488-rules-and-frequently-asked-questions-faq/), and post a description of your issue, along with logs posted to a site such as https://mclo.gs and post the link here. Please do not try to piggyback on years old topics that may or may not be your actual issue.

Please read the FAQ and post logs as described there. Even problems that look the same are not always the same, and logs are needed to discover what is going wrong.

These are the Minecraft Forge forums, Neoforge is not support here. You would best be served seeking support on (I believe) the Neoforge discord.

Please read the FAQ, and post logs to an external site such as https://mclo.gs and then post the link to them here. I put your log in a spoiler to avoid a massive wall of text for people to scroll through. You have mods that do not work on a dedicated server. Search through your log for "invalid dist" (without the quotes), and each spot you find it will mention a mod that does not work on a dedicated server.

Please read the FAQ and post logs as described there, they may contain information that will help discern the source of the issue.

These are the Minecraft Forge forums, and your modpack runs on Fabric, which is not supported here. You would be best served seeking support wherever fabric support is provided.

Neoforge is not supported on these forums, the best place to get support for Neoforge is from Neoforge.

I'm not sure you can update a mod just by changing the mod.toml, I'm not sure of all the changes, but I would imagine that the code would need to be changed to match any updates/changes from 1.18.2 -> 1.20.1 You could try sharing the full log (instructions on doing so in the FAQ) and seeing if anyone sees any fixable errors.

Always post new logs (to an external site, and posting the link here, as described in the FAQ) after removing mods/trying something to fix it.

Neoforge is not supported here, I would start by looking at https://neoforged.net/ for support
