Hello, I have a problem with the game launcher. I recovered the complete game file from my other computer (the game is up to date and complete, works fine) I have set the path but at 97% the launcher shows "connection lost, reconnecting ..." I have already whitelisted the game and the game folder, but also disabled antivirus, firewall, windows defender, etc. I don't know what to do, I tried a lot of things, can someone help me? moreover I had to take the game folder from my other pc because it was not downloading and I already had this "lost connection" problem

The game is already add in the white list (check picture). I have remove the checkmark frome attribute but it come back everytime. I'm from France and my internet connection is fine. I've tried to download the game from the website using the launcher but i have "error, connection closed"
