A critical error has occurred and the process must be terminated

So I have seen a lot of post regarding this issue and have not seen a single way to resolve it. I have formatted by laptop and reinstalled, even installed it on different computers but in the end the following error occurs 3-4 times in a game. This error requires me to re-open league and reload into the game. It has started with a recent client update and has not been resolved since. Any help in resolving this issue would be greatly appreciated.
