In rare situations, Via might not start due to a corrupted preferences file. To solve the issue, you need to delete your preferences file.

On Windows

Via stores its preferences within the user’s AppData directory. The exact location of this directory might change between the different versions of Windows, even depending if your user profile is a local one or managed in a corporate network environment. For many local installations, you’ll likely find it in a place very similar to C:\Users\username\AppData\Local\via. Remove (or rename) the file preferences.xml in that directory and try to start Via again.

On macOS

In the Finder, open the menu Go and press the alt (option) key. An additional entry labelled Library will appear, select it. In the opening directory structure, find the folder Preferences and in there the folder via. Remove (or rename) the file preferences.xml from that directory and try to start Via again.

On Linux

Remove (or rename) the file ~/.via/preferences.xml and try to start Via again.
