+ticket: MTM-65299
+version: 1023.4.1
+---
+In some cases, the user's preferred language was stored in an unexpected format in the user object (as an object instead of a string). The UI implementation expected a string and couldn't handle an object. As a result, initializing of the UI application failed, and the user ended up on a blank screen.
+
+This behavior has been adjusted and the application will initialize in these cases as expected.
