TFT first champ select not loading

Hello there, this is my first post and sadly it is a complaint. I am having problems with teamfight tactics. Whenever i join the game and should be send to the first champ select I start having connection issues, leaving me with taking a random champion [sg-ahri-1] . It all works fine afterwards its just the first champ select that does this. If anyone knows a solution for this please tell me as fast as possible.
