Discord Application will block left/right clicks inside LoL.
I just played a game where suddenly I was unable to right/left click anywhere inside the game. I tried restarting the game, I tried unplugging my mouse, and restarting my pc. The game was over and I wasn't able to help my team for the last 2-3 minutes, but we were losing anyway so it's ok.
I did some googling and kept opening practice tool games to see if anything would work. I tried a different mouse. I tried every USB port on my PC for my mouse. I thought about uninstalling and reinstalling, but I saw on google that other people with the issue were unable to fix it by relogging. There were no solutions anywhere except for one person who had a similar issue . This guy said that he was unable to left/right click until he closed out of Discord.
I tried closing out of Discord, and suddenly, I can click again.
This is bizarre to me, and I have no idea why this would happen, but I guess I'm not using Discord anymore when I play League.
To clarify: I was able to click in the LoL client and any other application on my pc, but once I loaded into the game, my clicks wouldn't register.
