opening up mod menu and clicking on the settings button of this mod makes the game crash with following error:

• The game crashed whilst mouseclicked event handler
• Error: java.lang.NoSuchMethodError: 'void net.minecraft.class_1735.method_48931(net.minecraft.class_1799)'
• Exit Code: -1073740791

im using the latest files:

• fabric-api-0.90.7+1.20.2.jar
• modmenu-8.0.0.jar
• smoothswapping-0.9.2-1.20.1-fabric.jar

Thanks for the report, thats really strange, it works in my dev environment but doesn't work when build. I have to look into this.

I've uploaded a new version, which hopefully should fix the issue

it sure does. :)
