Hello , sorry about your problems. My name is Marco and I will do my best to help you.
In the language and region settings, you must also put the languages below the keyboard option.
Select the Start > Settings > Time & language > Language & region.
Select the language that has the keyboard you want, then select Options.
Select Add a keyboard and choose the keyboard you want to add. If you don't see the keyboard you want, you may have to add a new language to get additional options. If this is the case, go on to step 4.
Return to the Language settings page, go to Preferred languages, then select Add a language.
Choose the language you want to use from the list, then select Next.
Review any language features you want to set up or install, and select Install.
