Hi! Was just having this issue, but I managed to find out how to get to the directory on Mac. Folder is in Library/Application Support/Godot/app_userdata/PNGTuberPlus. To get to the Library click on to your desktop, and you'll find there's a bar that has a button called Go. Click that, hold option, and the Library will appear. If you're having troubles finding the Go button, it's on the same bar the wifi icon is located on, left side of the screen. Hope that helps! Only managed to find this by looking through a bunch of old posts until I saw someone else describing the same issue.
