keyboard not working and stuff

@farshad_vcf_71;  Please read @mcsupersport's post again.  Your issue may have nothing to do with DAI, or FIFA, (which has a completely separate forum.)  The symptoms you describe point to a different program on your computer as the cause.  So even though you could play it successfully before, and nothing changed with your game, some other a new/updated program could now be interfering.  The fact that you have been "digging the net for couple past weeks" without finding a solution is an indication that this is not a "global" problem.

We (the folk who try to help others) know that the chat programs "Discord" and "TeamViewer" can cause problems.  And in certain cases the "Origin" overlay itself is the culprit.  Also on the list of "usual suspects" for this kind of thing are the utility programs for certain Razer, Steelcase, and Logitech hardware.  But there may be others.

Lastly, you haven't provided any details about your environment. A DXdiag report would help.  See item 2. in this post which is pinned at the top of this forum:

How to post the relevant info when you create a question

Ok, lets look into the tech forums for Fifa, DAI, MEA and SWBattleFront2....

First one or two pages of each forum....and see how many posts are about Keyboard issues on them....

Fifa 16....one post, which @farshad_vcf_71 already posted in dated from around 2015 or 2016, and edited to say it started working.

Fifa 17 ....zero posts on 2 pages.

Fifa 18....one post, with no response from OP after EA community manager posted there last Wednesday.

Fifa 19.....zero posts 2 pages

MEA.....zero posts 2 pages

DAI....well that is here, and you found the post about it and the listed fix.

SWBF2...one thread, and guess what, posted fix was Teamviewer disabled, with people reporting Discord and Origin overlay also causing issues....seems mixed on which causing most issue.

So the idea that there is some MAJOR GLOBAL ISSUE is just false.  There is a known issue between frostbite based games and things that put on overlays(aka outside programs interfering with the game), such as teamviewer, discord and Origin, which has already been made plain in this very thread.  So if you wish to fix your issue, I suggest you spend time posting the info needed to diagnose it, but please use the correct forum.  I would look very carefully into any program that hooks into the game and has an overlay that can be accessed ingame....such as discord, teamviewer, Origin, Geforce gaming evolved, steam, or any other.
