[CLIENT] Can not join a game lobby of Nomal/Ranked Draft Games

Hello reader,

after several months of playing League bugfree I encountered a severe problem. The main problem is that after I accept a game invite, I do not get into the game lobby of a Draft Game. I do get the game invite and can accept it but after accepting it, the main body of the launcher just turns black. My friends see the green check mark next to my name, but they do not see me in the lobby. In addition I can click on the crossmark at the top right to 'leave' the lobby. When I do that, I just get returned to the main screen of the launcher. Even after multiple attemps of 'leaving' and reinviting I do not show up in the lobby, which is also the reason why they can not start the queue. If I then decide to play Blind games instead, I can join the lobby and we can start the queue, but during champion select the whole launcher, except the border, turns black. I can still move the window around and hear the champ select music but I can not interact with the black launcher.

This Bug has been there for several months and I do not know how to permanently fix it or create it. It mostly happens when I start the launcher for the first time of the day. I found out a temporary fix though: You can use the** repair function** of the launcher to fix it for a short amount of time but in the end it will come back. This bug also appears after patching the game to the newest patch(e.g: 6.10 -> 6.11). Recently this bug has been coming more and more often. Sometimes it comes up when I start the launcher the first time for the day or it also shows up after I had played some games on the same day.

I have also tried to find out a permanent fix, by deleting the ..\League of Legends\RADS\last_versions ; ..\League of Legends\RADS\projects\lol_patcher ; ..\League of Legends\RADS\system\launcher.cfg; but the mentioned attemps did not even solve ** fix the problem temporaryly**.

At the moment I deleted ..\League of Legends\RADS\projects\lol_air_client and ..\League of Legends\RADS\projects\lol_launcher. Deleting both seems to fix the problem temporaryly but I am going to wait and see if the problem comes back and respond accordingly.

Thank you for your attention and have a bugfree day :)

PS: This is my first bugreport, please forgive my mistakes.
