Freezing At Title Screen (PC)

At some point playing MCC, I left the lobby after finishing a game, I then couldn’t see my continuation in the Seasons or even see my rank/progression. I assumed it was just a small bug like I’ve had before. But when I tried joining a new match, I couldn’t get past (Trying to matchmake). I exited the game entirely to reset it, only to find everytime it asks me to hit any key, I see the buffer icon to then seeing it freeze, having to end it through task manager.

Does anyone know a solution to this problem? Thank you.
