I just found out a very strange but working fix for me on another forum. It's because I had a Windows 10 USB Stick in one of my port. I was reading that a guy was having a USB stick of Windows 11 in his plugged USB port, and since he disconnected it, it worked. So I realised that yesterday I plugged in a USB stick of Windows 10. I did unplug it, restarted the game, anndd it's working again! Weird but effective.
I haven't been able to get into the game for two days now, and just came across your post while looking for answers. Tried all the rebooting router, modem, computer, flush dns tricks. Unplugged my usb stick and just like that I'm back in. Thank you for posting this. Crazy that something like that would cause this.
