We’re currently in the process of deploying a 17.2.2 client patch that will address the following items:

• Fixed a bug that would cause a crash on mobile when clicking the eye to see who is spectating.
• Fixed a few various issues that would lock the game state when playing certain cards from hand.
• Fixed a bug where some players in Europe were only given the option of Warrior as their free deck after graduating the new player ranks.
• Fixed a bug where the shop would be closed when launching Hearthstone due to a missing runtime dependency.

If the shop is still closed after updating to 17.2.2, try swapping to another region on the launcher and swapping back before opening Hearthstone again.
