EBE 0.2 conflicts with Optifabric when opening settings screen. I think it's because of the Configuration Screen added to the 0.2 version. Here is the error log: https://pastebin.com/raw/JyVDfxDN

I think it would be better to add it to Modmenu Screen than to add Configuration Screen to Settings Screen.

does this happen without fabric zero? (it's known to cause issues sometimes)

No this is a known issue and is already fixed in development, next release will fix this and also let you access the screen from Mod Menu

Fixed in 0.3.1
