Critical error

The game crashes and this message pops up: " A critical error has occurred and the process must be terminated. This is usually due to the result of incompatible third party software being installed on your machine. Please disable any overlay, streaming, or experience 'enhancement' software. additionally, you may need to whitelist this application with your installed security software. if you need further assistance, please visit the support website for help. " This happened a few days ago while trying to play aram, I had discord open in the background. I disabled the overlay but it crashed again anyway. I tried closing out of discord altogether and restarting league and it happened again. I restarted my computer and it happened again. By the time I was able to play without crashing (i lost track of how many attempts to relog) the game was already over but it didn't crash again after it.

Between then and now I've played dozens of games and nothing has been wrong but suddenly the issue is back and I cannot play no matter what I do. Both instances have been when I tried playing aram, however I have been able to successfully play through a full aram between the two occurrences. I have also tried playing the tutorial after a game where this error has occurred and I crash out of that as well. Doing a full repair hasn't done anything either.

Any help would be appreciated, Thanks.
