Immediately after the 30.2 update Hearthstone starts up without visuals. There is a flash of the tavern welcome screen then everything goes black, the audio plays fine, but none of the buttons (bottom-left & -right) are active. I have to use Cmd-Q to quit the app. This happened once before a few months ago & I thought it was resolved. Have repaired, uninstalled & even deleted the .plist file in my system to no effect… Playing on MacBookPro-2021 with MacOS Sonoma updated
The CMD-Spacebar keys took me into command center where I could select windowed mode and GAME ON! No response from developers/tech support… ;-(
