[2023] Random Server Issues But Only For Me (my router is fine, no problems playing anything else)

I have been playing For Honor for a long time. In the middle of a random game (2-1 btw but that doesn't matter) and my game randomly boots me back to menu with no error or anything. I literally just had a matchmaking ban after that too. Since then, every time I boot up the game, I get error code 0002001503 after I try to start any matchmaking. the game boots fine. I can roll through all of the menus and customize infinite heroes, but whenever I try to start a match of anything, the game either never connects or gives me error code 0002001503. I have been unable to play the game for 2 weeks on my PC, despite being able to boot and play perfectly fine on my series X. What is going on? I uninstalled and reinstalled the game, checked everywhere online, and even contacted support to practically no avail.
