Fix your client

Specific example? Like I know that recently after a game starts when I am in borderless the client won't load until I go into task manager and end task and then in the main client it will say Reconnect. That's what I have been doing to solve it. Has been happening on the PBE client and the regular one for me, if that's what you mean. Been happening since 2 most recent patches.

I feel you. I've been getting booted from the game right after champion select.

All I get is my home screen of the client saying "Game still in process" with no option to reconnect.

I have probably played 20 games in the last two weeks. And have been booted from at least 25 more. I report the bug every time but nothing has come of it.
