[Bug]: Locale is not loaded causing crashes on pages where date is used

[Cloud11PL]

Description of the issue

While using Dashboard locally in dev mode I noticed that sometimes some pages crashed when entered. The errors in console were typically related to useDateLocalize, DateTime and everything date and locale related.

I managed to fix it by setting locale local storage item to en. If it is undefined (default behaviour) then dashboard doesn't work. You can try it by entering product details page, removing locale key from ls and refreshing the page.

Here are some errors from console

Uncaught TypeError: moment(...).locale(...).format is not a function

Removing the space after LOCALE_CODE env value fixed the problem for me

- LOCALE_CODE="EN" 
+ LOCALE_CODE="EN"

I am also stuck in same issue. Please let me know if anyone gets the solution.

@SaujanyaSh In your browser you need to add locale of value en to localStorage
