I cannot join any game.

Reproduce: Enter a queue (I've tested in Summoner's Rift, normal game and custom game with bots) Select a champion, lock-in, wait for game to start League minimizes itself to an icon on the taskbar Click on it to see "In Game - Game Still in Progress." Exit out of game, relogin, "You have left a game in progress. Please reconnect to the game" Press reconnect button League minimizes itself to an icon on the taskbar Click on icon and get the same "You have left a game in progress. Please reconnect to the game"

When I exit out of the game, restart computer, relogin to lol, it still says "You have left a game in progress. Please reconnect to the game". It will continue to stay that way until the match is over. This only happens during a normal game in SR (Summoner's Rift). I haven't tried any other maps other than SR. After the match is over, I relogin and check my match history and see that it counted as a Leave (normal game).

I get similar problems when creating a custom game with bots. Reproduce: Create custom game with bots Select a champion, lock-in, wait for game to start League minimizes itself to an icon on the taskbar Click on it to see "In Game - Game Still in Progress." Exit out of game, relogin, "You have left a game in progress. Please reconnect to the game" Press reconnect button League minimizes itself to an icon on the taskbar Click on icon and received "Error Active Game was not found" Click on OK twice Takes me back to "You have left a game in progress. Please reconnect to the game" Press reconnect button League minimizes itself to an icon on the taskbar Click on icon and received "Error Active Game was not found" Click on OK twice

Basically if I click OK twice and reconnect it goes back in between the 2 errors "You have left a game in progress. Please reconnect to the game" and "Error Active Game was not found"

When I check my match history, the normal game counted as a Leave, but my custom bot game didn't show up in match history. Please help me fix this. I would provide logs but I have no idea how to do that. By the way, I don't know if it makes any difference but at the time when this happened, Windows update was installing "Windows defender definitions update", I was updating flash player to 16.0.0.296 which I found out was vulnerable and still is, and I also had ms excel opened.

EDIT 1:

I finally fixed the issue. I think it's because of corrupted game files. I uninstalled lol, defragged my computer, and resinstalled lol now the issue is resolved. I can finally join a game.
