Constant Challenge Failed Error when playing online.

[wbm27_PSN]

I need some help. Over the last couple of days I've been unable to play another variation of MLBTS online and I have no idea what else to do, hence why I came here.
I restarted my internet and my PS5 both, deleted and reinstalled the game, restored licenses, and made sure my PS+ works, and still nothing. Every attempt ends in "Challenge Failed" so I don't know what else to do. I'm going to call PlayStation tomorrow or Tuesday, but I wanted to know if anyone else has had this issue. I'm completely stuck and need help.
