a critical error has occurred and the process must be terminated

its hapens to me too... but durting the game and i dont know how to resolve the problem

Happens to me too. In middle of a match. 3 times it happened. Can confirm that it is being caused by League.

I'm having the same issue. I've submitted a ticket so I'm just waiting to hear back from riot. I don't feel comfortable playing in the mean time.

Same. Ran into it last night.

This is pissing me off and I lost a ranked game that I would have won because of this crap. Hope riot fixes their garbage client.

Hi guys. Thank you for the reports. I have seen in the Brazilian server forum that there was a anti-cheat security update. There are many people with problems because of conflict with other programs, such as internet banking plugin. There is still no solution and I still do not play.

Yeah, same thing has been happening to me for the last few weeks. It happens to me in the middle of the game. Riot has asked that you upload dump files from the game in their pinned thread so they can investigate.

Unfortunately, it seems they have stopped responding though. Very frustrating.

Same problem. Lost a ranked, lost a duo mate and cannot fix it

new issue as of new patch. me and 2 friends also having it. Think patch issue?

Happened to me too just now. When I hit shift f to level up

WTF Riot!??! Just started having these issues after the "patch" you did... Did some research and found some posts from like 5 MONTHS AGO! and it still hasn't been fixed?! WTF? WTF? WTF? Kinda horse shit that every other game i play it freaking crashes, usually right at the end and causes a lose, OH and if my team happens to win I get hit with this bullshit that I don't get any credit because of AFK or leaving the match... Like it was my choice, it was your damn Kmart pos duct taped patch!

Kinda disappointing, I came back to play again to see all the new stuff... Pull your heads out of your ass and please fix this. Thank you and hope you have a great day!

P.S. DO NOT SAY YOU NEED THE FILES BECAUSE THE SHIT I LOOKED UP, 100s OF PEOPLE WERE POSTING THE ERROR FILE FOR YOU!.

Today it happened to me the same thing 3 matches in a row and i couldn't play more than 5 minutes. Not only i lost my rank but i also got lots of bans. Please someome help!

problem SOLVED. I did some procedures on my computer. Firstly I updated all the drivers by the program "Drive Booster". After that, I started the League of Legends by way of compatibility with Windows 8 (right click, properties, compatibility, and select to start the program via compatibility mode. In other games that also came back to work. I ran tests and found that Windows indicated incompatibility with the League of Legends. I do not know why that happened. Thank you guys!!
