Same issue after installing Ventura. A "fix" isn't good enough for me: I want to know why it's happening and/or how I can try to prevent it in the future (seems to be a common problem w/ MacOS upgrades, based on internet searching; it's pathetic that Apple can't fix this!), e.g., should I "hide" a directory by prefixing it with a "." before installing updates and then unhide it afterward? There's got to be a way to prevent this from happening (even if Apple won't figure it out).
