game crashing at 100% load screen

So there is a problem with the league client that sometimes my league game on the loading screen would be on 100% and I'm sitting in front of the computer waiting for it to start, and then the game wouldn't start because it had crashed. The loading screen looks like a completely normal loading screen that had reached 100% and it doesn't tell you that it had crashed. after about 5 minutes I would figure out that the client had crashed and I would have to restart it, but at this point, my team had already remade or you are extremely behind for the whole game and I lose LP or possibly have gotten a leave buster for riot's client error. This problem had been reoccurring for years for me, happens every couple months or so but im just extremely tilted rn bc I lost a rank game because of this.
