Game Crashes when i search @open in JEI with OpenBlocks Installed

[TopazGaming]

So I am playing a modpack called FTB Presents SkyFactory 3 and it doesn't come with the OpenBlocks Mod Installed and I didn't know that so I searched @OPEN in JEI and found out that open blocks wasn't installed so installed it then relaunched the game and when I searched @OPEN it crashes and I know optifine helps with some texture problems and I thought it might be a texture problem so I installed optifine and it still crashed. Is there an easy fix for this?
