constantly forced to uninstall and reinstall to play after closing the client

as I am trying to take better care of my computer, I tuck it in and put it to bed every night now, before I fall asleep that is my plan at least

each and every time i close the league of legends client though, upon attempting to restart and open it in the morning/whenever, I'm met with the small league of legends logo for about 2-4 seconds before it disappears and then.......silence

yes, i know a similar bug occurred this year, yes i know the solution to that bug involves opening task manager and ending any league tasks keeping it from opening, but when i investigate i find that no such program is running. its becoming quite bothersome. i also noticed that each time i try to open it before it appears that the impending doom has become current, i see a harmless little window that says "checking for corruption". i have to assume that the corruption usually gets the better of the client because once i see that, i know for sure that im not playing again until i click delete on the desktop icon and find the league installer and do the whole process over again.

this is an avengers level threat, please someone ANYONE help me understand what in my power i can do to fix this so I don't have to risk my computer lul
