Problem With Resource Pack

For some reason when ever I try to download the resource pack for wynncraft it either crashes the game or whenever I enable the resource pack to download automatically it stops the game and says illegal argument. Can anyone help me please?

 

Hmm... From what I see in that screenshot, the problem might be on your side.
I googled a solution for that error and I found a major one, so let me explain here.

The problem happening here is there's no folder to download the server resource pack and the game cannot create it somehow. So you need to make it yourself.
1. Open your minecraft directly, you can open that from Options -> Resource Packs -> Open resource pack folder, that opens up .minecraft/resourcepacks
2. Create a folder named server-resource-packs, inside of your .minecraft directly.
Then try restarting your game, and join the server again. Also make sure the Server Resource Pack option is enabled: https://forums.wynncraft.com/threads/cant-play-wynncraft-because-of-the-pack-heres-how-to-fix.98023/
