Didnt may open pc-version hs

Last night I was dusting my cards, after that my game froze. I restarted it - and could not enter the game. The Heartstone logo appeared, there was no Battle, the emblem blinked, but nothing happened. then - it was written. “Your game timed out as it was requesting data from the Hearthstone utility service” HS: CT; NetCacheDecks = 0; NetCacheCollection = 0; NetCacheCardValues ​​= 1
a couple of hours passed. I noticed that the game in other regions (Asia and America) starts and everything is fine. But if I chose my region - Europe, nothing happened. After installing the update on my phone, I can log into my account. But there was a rollback, when a failure occurred, I had 23 thousand dust. and now 17k. But the PC version still does not enter
I tried :
1.reinstalling the game
2.deleting the cache no battle
3.reinstalling battle no
4. check for integrity and repair of the heart stone.
nothing helped.
