For anyone interested, I finally managed to fix the issue, and yes without help, because who cares, am I right?
The Fix: on AMD MediaTek wi-fi driver, uninstall driver, reinstall, this will firstly fix broken DNS, yes win 11 update broke the Wi-Fi driver DNS, and because of this no servers/connection or overlay issue for the SWTOR launcher.
After driver is installed, go to network adapters and pick IP4, for some reason SWTOR works better with IP4, and not both IP4 and IP6 active.Manually add DNS 1.1.1.1 primary and secondary 8.8.8.8, this will fix DNS SWTOR connection issue. After this reboot.
You can actually check if this works using CMD and bash nslookup google.com. If it replies with server one.one.one.one etc. You are good to go. start SWTOR launcher and enjoy.
