Just a rant.

IIRC when Ventura cames it was a disaster for RSB since on Monterey this 
worked and on Ventura it stopped. IIRC less RAM on system shows more 
sensibility to Ventura problems. And IIRC you were the person who solved 
this somehow.
Does this mean we're back to the original state with Ventura making 
troubles again? I'm not sure if this is even technically possible 
(partly due to how Apple supports OS reverts) to test every version of 
Ventura released by Apple to see reliably if whole family is sick or 
there are some versions which may be recommended for use. E.g. Ventura 
spans from 13.0 to 13.5 already...
Perhaps doable on VM...
