You must check the shouldrender method in your renderer class. If you can't find it, try searching for it in the parent class (that minecraft has). All I know is that BYG had a similar issue and it was with other mods. I didn't think to look at the crash report back then.

Are you sure that you have the mixins defined in a mixins file? Are you sure that your build.gradle recognizes the file?

It's saying that an "entityrender" variable is null, check that. Funnily enough, I once played on a server where the BYG boats crashed the game and they had to make a rule where crafting BYG boats was not allowed, but that was in 1.16.5.

Try running the jar from command prompt or downgrading your java to Java 17.

Try Jarfix I guess?

Try this tutorial, it may help you.

Try putting the installer in a separate folder and run it again. You should then have no problem finding the log.

Can you send the log? It's usually in the same folder as the installer.

Can you try posting the log? (I saw all of the other urls and legit thought this was a spam post.)

You might want to check the change logs of mods that you know change world gen. I personally play on a server that seems to have this problem and they sort of just live with it. ¯\_(ツ)_/¯ Nobody really goes to those regions anyway because we have Waystones. But this isn't about my life story; check the change logs between the 1.18.1 and 1.18.2 versions of worldgen-changing mods and see if there are any recorded differences. Additionally, you could try updating all of the mods to the latest 1.18.1 versions and then making the leap to their 1.18.2 earliest versions (the earliest that came after the 1.18.1 latest).

This doesn't seem to be forge related.

I believe that you need to define a transparent-cutout rending mode or something. I suggest looking at how flowers are rendered (if you haven't done that already).

1.16.5 is no longer supported here. We only support 1.18.x and 1.19.x.

You can use BYG as a reference.

Seems to be SuperMartijn's Config Lib. You might want to try another config mod (Configured is my personal favorite, but you can also configure mods through Create if you have that installed).

The Forge forums don't support Fabric (just Forge), please ask where you might receive support.

Since I am unable to access the paste, I cannot help you (someone else will have to).

Either way, I can't access it. Can you post it on Gist or Pastebin?

Paste.ee has been flagged as malware. Can you post the logs somewhere else?

You need to add a new AI task to the zombie (probably via mixins). Here is a similar example for creepers. (This goes with it.)

Can you send the launcher log?

You have to use run the jar with java (which you must download if you haven't already).

1.16.5 is no longer supported here. We only support 1.18.x and 1.19.x.

So you want to open a GUI when right clicking on a certain block with a certain item in hand?
