Changing language fails with error "Translation file for XYZ was empty or missing"

In Minecraft 26.3‑Snapshot7, the language switching feature is broken. When I navigate to the language settings screen and select a different language, the game fails to apply the selected language. The interface remains in the original language with no visible changes. I have made a screen recording to reproduce this bug. The video shows my process: opening settings, entering the language menu, attempting to switch languages, and proving that the UI language never updates after making a selection. Expected behaviour: After choosing another language and confirming, the entire game interface should switch to the selected language immediately. Actual behaviour: No language change takes effect after selecting a new language. Please investigate this bug for the 26.3‑Snapshot7 build. Thank you.
