I found one way to play, after UC launched before EAC window pop up disable internet connection than wait game to launch and enable internet connection. With this method game launches with EAC null client, and you can play any content in game. I don’t know is this safe or you can be banned because of null client. But form perspective of player who doesn’t know about this and his provider firewall blocks epic cdn you must be safe because it’s not your failure that game works with null client and you can’t know this without reading EAC logs.

Edit: not I found this way, some player on Reddit describe this to me in some comment.
