Unable to switch language to English
Description
I cannot switch back KiCad to English.
My default system language is Spanish. I selected Spanish for a while to check the translation. Everything went alright.
Now it is impossible to switch to English.
If I select language "default" it stays in Spanish. What is logical since Spanish is my system default language.
If I select English, this message apears:
What is also logical since there is no package kicad-locale-en
BUT switch to English works perfectly in v5.1.8 installed in the same computer.
