Unable to start up patcher for new update

I clicked on my league shortcut and the icon popped up but then disappeared and the patcher did not open . I tried multiple times and even restarted my pc and nothing happened. After a problem like this, i tried going on to my pbe account and the patcher did open and it works! Rito pls fix i need to try new devourer NOT ON PBE to be clear the problem here is i am launching league but nothing happens other than the logo/icon appearing and then disappearing
