I recently upgraded my Mac OS to Monterey 12.7.8, after which I reinstalled BG3 via Steam. Now, when I click on "START" on the Steam page, I get a box which tells me "Verifying "Baldur's Gate 3"; the verification lasts for a very long time (over an hour), and when the bar is full... nothing happens. The Steam Library page suggests that the game is running, but nothing appears on my desktop. The BG symbol also appears on my active bar, but clicking on it does nothing. Rebooting and starting over also does nothing. Any suggestions?
