Start at PowerLauncher.SettingsReader and follow the startup path into SettingsUtils.GetSettingsOrDefault, BasePTModuleSettings.ToJsonString, and SettingsSerializationContext. Reproduce the startup failure on PowerToys 0.99.1.0 and determine why PowerDisplay.Models cannot be loaded; done means PowerToys Run starts normally without this FileNotFoundException.
