Stack trace from %LocalAppData%/PSLauncher/logs/app-*.log pinpointed the
exact line:
System.InvalidOperationException: Une liaison TwoWay ou OneWayToSource
ne peut pas fonctionner sur la propriété en lecture seule
'LauncherVersion' de type SettingsViewModel.
WPF's <Run Text="{Binding ...}"> defaults to TwoWay binding (unlike
TextBlock.Text which defaults to OneWay). Bound to a `{ get; }`-only
property like LauncherVersion, the binding system tries to install a
back-channel writer at AttachToContext time, fails, and crashes the
whole window during ShowDialog().
Fix: explicit Mode=OneWay on the affected <Run>. The other read-only
view-model properties used in this dialog (MachineId, LogsDirectory,
CacheDirectory, LicenseInfo) are bound through TextBlock.Text and are
unaffected.
For posterity: serilog file sink + AppDomain.UnhandledException hook
captured the failure with the full stack — exactly the diagnostic flow
v0.5 was meant to enable.
