It is an issue with open-parties-and-claims-forge Looks like this mod is trying to load an invalid or missing Spain language file If your Launcher or System is set to this language, make a test with changing it in the Launcher Or remove open-parties-and-claims-forge

Remove survivality

I don't think so You also can work with adding mods groups - so add 5 to 10 mods and remember these - if the game crash, check these mods You can also add crash-reports here with sites like https://mclo.gs/ You will find these in the crash-report folder - if there is no crash-report, use the latest.log from the logs folder

Use such a pre-made modpack as working base - allow content management and add new mods one by one

Did you try older builds? https://www.curseforge.com/minecraft/mc-mods/unionlib/files/all?page=1&pageSize=20&version=1.21.1&gameVersionTypeId=1

The config folder is in the same folder as the mods folder if you are using the original Launcher, then it is C:\Users\NAME\AppData\Roaming\.minecraft\config\

The config of UnionLib is invalid Delete the config of it (config folder) - if there is no change, try other builds of UnionLib

You are using Create 6 - some addons are not compatible with it Remove all addons and add these one by one littlecontraptions is mentioned - keep this one removed

Remove vanquisher_spirit

Add the latest.log from your logs-folder
