Game Unplayable – Kicked for Inactivity, EA App & PC Lose Connection

Hello,

I don’t know what to do anymore, so I’m turning to the forum for help.
I bought BF6 last weekend and was able to play without any problems the first evening. Then, the next day, I played for about an hour with no issues. I was on Discord with a friend, and suddenly the game started acting up—my Discord cut out, then I got disconnected from the match with a message saying I was kicked for inactivity (I've attached screenshots).

So, I looked online, checked the forums, etc. I uninstalled and reinstalled both the EA App and BF6. I followed EA remote support's “advice” not to play over Wi-Fi. I don’t use a VPN and I don’t have any of the usual things that cause problems. Still, no fix.
EA has provided zero support—all their “contact us” buttons just redirect to the forum (which is honestly shameful).

I tried digging into my Wi-Fi settings, DNS, and more, but nothing works. I keep getting the same error message, the EA App disconnects, and my whole PC loses connection—it even kicks me off Discord.

For the record, I don’t have this problem with any other games. I have a 1350 Mbps connection, and my PC is well above the recommended specs for BF6.

At this point, I just don’t know what else to try. I can’t even get a refund to buy the game on Steam because I’ve passed the refund window—and since EA has no real customer support, I’m completely stuck.

Please help!
