To remove the user settings completely on the Mac just delete ~/Library/Application Support/Wappler
This will indeed also remove all your Wappler projects, but because the projects settings are stored in the project folder (in hidden .wappler folder) you can easily add them again by “open existing folder” option in the projects manager
After launching the new Wappler you will just have to sign in with the user profile and your license will be activated again
