I'm getting this as well using runClient and trying to launch the client from the Mojang launcher (forged) without any other mods added.

Ok, I found I had the wrong value for the loaderVersion in mods.toml file.   Changed it from 24 to 25 and launching works.

 

 

loaderVersion="[25,)" #mandatory (24 is current forge version)

@kwpugh Don’t hijack threads, make your own. This is one of the (very) rare cases in which you have the same issue (probably), but it’s a good idea to make your own thread anyway.

When you update your mod, be sure to update your mods.toml file.

Also, don’t use the runClient task, always use the launch/run configs from within your IDE
