[CRASH] [CLIENT] Game crashes on certain champs, friend's list won't update

Biggest problem is that when i engage, my game crashes. it happens mostly, if not only on azir and lee sin. when i shuffle in my game will crash or when i second cast q on lee it'll crash. happened on lucian once as well. happens 99% of the time when i'm in the bot lane, and one time in mid when i took a lee q under tower. it happens randomly, i'll go a day without crashing then the next crashing every game. i'm not sure what causes it, but it happens mostly with lee sin second q cast.

as for my client, it doesnt update after i log in. like if someone logs in itll take forever for them to show up on my friends list, itll show people being in game when theyre not, people logged in when theyre not, and itll either fix itself in 30 seconds or never at all.

i've done the full repair and same shit.

oh and i can't minimize my client...also really annoying

i forgot to save a crash report, next crash i'll put it in this thread. thanks fam

EDIT i was in an aram and there was a lee sin on the enemy team...when he came in and combo'd my game crashed.
