[Crash/Client] Unable to enter a game. Flickering black load screen

twice today while loading into a game, it starts flickering the monitor black then showing just a black screen for League. It does this over and over until it just closes the window on its own. If I open up the task manager it always shows the game as not responding and i have to force close it. I was able to get into my first game today after 3 tries, but the second one marked me as an AFK/leaver even though im TRYING to get into the game (They rolled a remake)

Update: I was able to get in easier by switching from fullscreen to windowed/borderless. Its still sitting on a blank black screen for long periods, but it eventually connects.

This has all been with the new client
