Game language not supported (Dragon Age: Inquisition)

So, i have an XBOX Game Pass subscription, the account is linked to my EA account and there was no issues for me while playing Dragon Age: Origins and Dragon Age 2, but at the moment i am unable to launch the game (Dragon Age: Inquisition). 

At first, my language was fixed to Polish and Russian (due to EA account' region, i guess?), but due to my system language being English, i tried to fix the issue with mods and access English language. 

After that, i have encountered the issue: "Game language not supported". 

Since then, i have already tried to fully delete the game, re-install it, which did not help at all. 

I have also tried to repair the game several time, it tries to, but the situation does not change. 

It is possible to change the language in game' properties: just as repairing the game, it does download some files, but the situation does not change. 

Currently, i am unable to access the game even in the language that is different to my system language: game is unable to start in any way, which raises the question why to even bother with it. 

Any fix? As i stated, fully deleted the game previously, repaired and tried to change the language in properies, no effect.  

I have also contacted help.ea.com and created a ticket, but it was closed without any answer after 24h wait.
