I actually have installed ToneZ plugins yesterday and today I cannot start Cabbage anymore. The error is
Excuse my German , but I guess it is the same message as what this thread is concerned with but with ‘csoundLoadPlugins’ instead of ‘csoundGetInputName’.
From your post I guess there is a problem between Cabbage and ToneZ although (or because) both are based on Cabbage/CSound. Will it help to de-install ToneZ? (I fear it is not just deleting ToneZ.dll but maybe also some registry stuff.) Or better would be a way to avoid this error keeping it because ToneZ is really a great plugin!
PS: I am running Win 10 Pro, Cabbage 2.5.12 (stable 2.5.0 throws the same error), Csound 6.15.0
