Release hosts crash when loading localisation resources

In Objo Studio 26.5.7, apps that include localisation string resources under Resources/Strings/*.json can crash when launched through the bundled release runtime host. The failure occurs before the app window opens and reports that reflection-based System.Text.Json serialisation is disabled.

This affects resource-backed calls to Localise(...) in released/bundled host runs. Locale-aware formatting APIs such as Locale.FromIdentifier, number formatting, date formatting, and currency formatting are not affected.
