UT mode - Someone knows how to kick me out of the server

Especially when I almost won from behind, at very end of the game I have seen a lagging and after 2-3 seconds, then suddenly it showed I disconnected the server. When I reconnected to UT DNF message appeared. I don't believe this is a coincidence as this always happened when I almost won, especially from behind. My network is stable and I always play with LAN cable in PS5, and turned off cross play.

I guess someone knows how to kick you off (plug off LAN cable?), this happened with previous years but this year it is really common, 4-5 times in one night.....Looks like more and more kids learned the trick. Really frustrated, had to refunded the game to protect my heart. EA needs to take this seriously. At least, I won't but any other FCs as the problem is getting worse and worse.
