Random disconnection from champs playoff messed up my immortal evo

I was playing champs playoff and all of a sudden randomly disconnecting me from the server sending me back to the main menu with my ea account disconnected. To be honest, it is not the first time in this year having this issue but this time just totally messed up my playing experience.

My PS5 didn't show disconnection of my network, it connected to my high speed broadband network with a lan cable, all my internet connected devices didn't disconnect and  psn server is currently stable. I reconnected back to the game without any fix on my internet. So it is clearly your server is being unstable and disconnecting me. 

I currently won 2 playoffs and then with this disconnected game, I am one game quota short on completing the immortal evo objective.

PLEASE SEND SOMEONE TO HELP WITH THIS ISSUE.
