0xc0000005 wont let me even access the client

After Destiny 2 suddenly disappeared from my download after my laptop crashed, I started to reinstall it. I played a match of Rainbow and it worked fine. When i tried to open up the League Client I got the 0xc000006 notification. I tried the CCleaner and the commands. I updated my drivers, I tried the turn off DEP but that didn't work. I am not really a good tech person and the websites online haven't been that helpful at all. Please Help!
