Since about 11th of March 2021 (noticed a client update), MTG Arena is temporarily corrupting my install drive on Windows 10 (Insider Preview Build 21332, used to work just fine until the last maintenance/update). I start the game client, try to access the store or start a new game, i get the spinner which freezes (the game freezes) showing as Not Responding in task manager. At that point, my install drive start reporting incorrect folder sizes, some folders cannot be accessed..etc. The Data folder in MTG Arena ,for example, is empty. If Windows is restarted, everything reverts back to normal but the game is not playable for me anymore cause of this issue. Again, even with insider preview, this used to work until the last maintenance/update.
