[CRASH] Game crashes right after Champion Select

Had 4 defeats because of a mega bug that crashes league. Right after champion select the screen turns black, I get a LOL cursor and then whole windows 10 crashes and I can't even open task manager. the only thing I can do is log off. After loggin back in, i try to reconnect but the same black screen will happen. When I wait I evetuallly enter the post game chat where everyone is flaming me for ruining their time. I also lost a ton of LP and I am in low priority Qeue. Im doing everything I can to find fixes but nothing helps. I do everything I can to prevent this. I always start a custom game (because sometimes it crashes there too after champ select) before going into ranked but it seems to be totally random when this happens.

Please help me to fix this game breaking bug and resolve the 20 minute low priority qeue which should punish leavers and not a person who is a victim of these bugs.

Anyone has fixes for this? Tried to remove the logitech files (cause that couls supposedly cause the crash) but that didnt help.
