Technical launcher issue

So yesterday i pulled up league played some normals nothing was wrong, first game of ranked i tried to play today, i crashed 10 times, it failed to load due to an error and cost not only my team lp, but me a demote for something that i could not have prevented, I dont care you can demote me for this but i had a good team and they certainly dont deserve the lp loss because of this technical error that wasnt on my side
