Just recently I played the game for a bit, I revisited the profiles I made back when I speedran the game. But when I tried to play again later, the game would crash every time it tried to show the profiles. The only part of the game I could visit was multiplayer racing with both dogs being guests. I reinstalled the game twice, that didn't do anything. I assumed that the problem was with the game's save file, but I didn't know where it was. Out of curiosity I went to AppData\Roaming, where I found Ubisoft\PetzSports with the save file, called profiles.petz! I removed it, and the next time I ran the game it worked fine, though I had to lose my progress.
