(Steam, Windows 11 PC)

Experienced a game-ending bug when activating the +1 ability of Vivien Reid planeswalker (look at top four cards of library, pick land or creature, add to hand, return rest to bottom of deck). Game showed browser with top cards, including several viable options to select, but I was unable to click on any of the cards to select them. The game then appeared to confuse the browser and the battlefield; the battlefield had a "View Battlefield" button instead of "View Browser", and clicking it pulled up the browser view again, which in turn showed a "View Browser" button in the top right corner instead of "View Battlefield". Clicking "View Browser" pulled up a view of my library with revealed cards on top, but not in the window the game shows for selecting cards.

I could not navigate out of any of these screens to resolve or cancel Vivien Reid's ability or resume the game, but my countdown timer began ticking anyway. Since I could not take any action I had to concede. Video clip attached.
