I have just updated VEP 7 from build 1526 to 3310 on Mac Pro OS Ventura and all apps using it showed that VEP7 server is not present. I checked in VST folders and true, all VEP7 server VSTs disappeared, only components are installed. Panic! as I am at the end of the project for "yesterday". Luckily (and here chapeau bas for VSL) for each app there is an archive option allowing for reinstalling previous versions. So I saved myself by reinstalling build 1526.
WARNING! Installing Build 3310 on OS Ventura may put your work to stop until VSL corrects this bug.
TEMPORARY SOLUTION: use "Archive" option to install previous working build.
