Please don’t do that! I expect the Library Manager will copy the C13 private(!) VST Sounds to a common folder, then multiple / different version of that VST Sounds are seen by the Steinberg MediaBay Server and Cubase 13.
There must be something unusual going on here: content movement / preference modification / MediaBay uninstall / Windows domain server environment / just brainstorming / … I would like to understand it. The truth is hidden in the prefs, let me read them. We might discover some unsupported (installation) use-case leading to this scenario.
