LoL game client says "not responding" when opening. *FIX/SOLUTION!*

I've been having an issue with the Riot Client (specifically for League) for the last few days. I would try to load into a match, and my client would just say "not responding."

I found out it was due to the NVIDIA Gameplay overlay. Once I disabled it, my client loaded like normal and worked flawlessly as if nothing ever even happened.

If you're having the same issue, open: NVIDIA GeForce Experience > Settings (the cog in the top right) > General > In-Game Overlay > DISABLE IT.

I hope this helps! ❤️
