Looks like you are missing some mods that other mods require.

That does not look like a complete debug.log. You should post it to a paste site like hastebin or something, and then post the link to it here. However, I would remove optifine and see if that helps.

Have you made an item? That's the first step, an item that does nothing that you can hold in your (off)hand. After that, I guess it somewhat depends what passive effect you are looking for. Will this need to be applied on equip/removal? Or is it something that can be detected elsewhere (i.e. damage-taking event, checking for totem equipped, then reducing dmg)

Are you using the curseforge launcher? If so, you will need to go into the settings and enable the debug.log. I do not use the curseforge launcher, so cannot tell you the exact steps for how to do so.

Those logs do not look complete, they look as though they've been cut off. That second log doesn't even have a crash in it. When you have a lot of things and need to find the one(s) that are problematic, there's a method for doing it that's easier than 1 by 1: Remove half of the existing things, and put them aside. Run the program / game. Does the issue still exist? If YES: Repeat from step 1 with the current things. IF NO: Swap out the current things with the ones set aside, and repeat from step 1. Repeat this process until the problematic thing/s have been found.

Apologies, not sure how I thought it was still there, that line was from the old log, sorry. Broken or conflicting mixin(s). Honestly I can't tell which mod(s) exactly are doing it, so unless someone else knows, you'll have to trial and error remove mods and test to figure out which ones aren't working together. The joys of mod developers directly modfiying the minecraft code, weeee

That is either not the debug.log, or it is not complete. There is no crash present in that log you posted.

Search github for projects, many of them are open source and published for anyone to look at. There may be ways to reverse-engineer someone's code if they do not make the source available, but it's usually best to have permission/find open-source mods to look at.

Make sure you have the latest amd gpu drivers

This crash still uses optifine.

I'm not seeing that error in that log, it should tell you the mod using the improper character in the resourcelocation right around that error. Remove/update that mod,

Remove Optifine and try again, if it crashes again post a new log please. Also, logs are easier to read if you paste them to a paste site like hastebin or a github gist.

Post a debug.log, it will have the most information. And you do not need to make so many threads about the same issue, 1 will suffice.

Whichever mod is doing that (I don't see one named "ore") is breaking stuff. Can't have capital letters it item/mod IDs. If you can figure out which one it is, remove it. If you're not sure, you don't have too many mods, you can start removing one or a few at a time that seem likely and testing, putting back ones that don't affect the issue.

This usually means the configuration file is broken. You can either delete or rename it, and it should be recreated on the next run. You might run into more, so search your log for "failed to load" or "caused by" if it crashes again.

Need more information. Post your entire debug.log to a github gist or something, and then share the link here.

So how does later foge "break everything"? Based on this error, if you don't want to upgrade forge, then you need to downgrade puzzleslib to a version that'll accept your version of forge.

Looks like something broken in projectmmo, something is nothing when it shouldn't be. *maybe if you rename/delete the configs for it? It looks like it might be trying to read one that's broken.

Create a github account, if you do not have one. Go to gist.github.com Drag & drop the debug.log into the text area, and it will fill it in for you. You can also give it a name/description/etc. Click the create gist button at the bottom right Share the url of that page here, there's a dropdown button (I think it starts with 'Embed') that has shareable link option.

To be fair, Minecraft Forge has a discord server as well, and seems unfair to direct them elsewhere, especially from here. (that being said, I'd join both)

Wrong forums, this is for minecraft forge, not fabric. You will likely not find any help here.

First errors look like you are using mods that want a newer version of forge. Second errors looks like you have mods that are conflicting, trying to modify the same code or something. That's all I can guess, as the log does not look complete so there could be other stuff below that is missing.

You should create your own thread, with a link to your crash report, and a link to a github repo with your code. That will help someone to help you chances are your code is not the same as the original poster. Your mod is broken, possibly trying to use/register a point of interest? You should post a link to a github repo with your project in it, as trying to post just some of the code may leave out the important parts.

I'm not seeing any crashes or anything in that log. Try posting a link to your debug.log after it doesn't work, it should contain more useful information.
