@EA_Blueberry I did as you said and the game open, but I think I wasn't clear - my problem is matchmaking loop. The game is up to date and I double checked it in game - version 0.4.0.
I saw in this post that what cause the problem might be a missing update, so I check if I can update the game - and I was surprised to see that I can click update. After I did so, there is not really update that download or installed - just a message say that the game is playable.
Ingame while try to join a game, after the countdown I see my own specialist and then return to main menu.
Sometimes even the countdown bugged as it go to 4 for example and then jump to 10 and repeat.
