[BUG] Crash on Choosing non-translated languages

[ykis-0-0]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

First of all, to clarify the nature of this issue, this is NOT a translation request.

There are two problems:

1. The language selection drop-down have an option for "zh-HK", which does not have the i18n translations in /lib/i18n. (Personally I think it depends on the user's Windows language settings)

2. Out of curiosity I gave the erroneous "zh-HK" option a try, and upon restart it breaks completely, interface unable to be loaded, and only give me a white rectangle with a black bar

An Update: after manually messing with shared_perferences.json, it seems that all of the `zh` languages will cause this to happen*

Expected Behavior

1. Only languages with existing translation should appear in the language selection drop-down
2. Upon failure to load some form of error dialog should be shown? (If 1. got fixed this probably would be an non-issue though)

Steps To Reproduce

1. With Windows set to a language which i18n for this repo doesn't exist (in my case "zh-HK")
2. Go to the settings of the Distro Manager
3. Change language to that (not supposed to exist) option
4. Save and Restart
5. 💥
