Crash Report: https://pastebin.com/2hfwcZKd

It looks like you’re missing some dependencies, although I’m not sure what. Make sure all your mods/plugins have the mods/plugins they themselves require.

Also I see you’re using PEX, that plugin is abandoned and I’m not even sure it’s 1.12.2 compatible, you’ll want to use LuckPerms (It has a converter for PEX, although you may need to fix the ranking/weights).

I’ve also never even heard of some of these other mods/ plugins, you will need to check they’re 1.12.2 compatible too.

Hope this helps,
