Help please

ok, so today i played about 3 games, bot matches with star guardian lulu cosmic dusk zayah and dj sona i believe no problems, but then when i tried locking into the final boss veigar skin my client crashed, i was like ok, maybe a freak accident, so i closed and relogged, tried again same character and skin, crashed again, relogged did it again, crashed yet again, so i uninstalled client then reinstalled thinking maybe that was it, logged back in and picked arcade sona this time, crashed yet again, so i will be logging in and trying with a different skin, and if it works, you may have issues (bugs) with those skins, i am just trying to inform you, just to give feedback, i love this game, ive enjoyed it for many years so i am a bit upset with this new developement

thank you very much in advance
