League and whole computer freeze 5 to 10 minutes into the game with only solution - resetting the whole system.The only solution I found is pressing CTRL ALT DEL and just return to league after 5 minutes being afk.I am seeing a lot of posts recently about this topic and riot are working on fixing the problem.
**!!!!! EDIT: **Riot are on their way working on the problem, yet they helped us find an alternative temporary fix of it: Just disable your ANTIVIRUS and start repatching with the HEXTECH TOOL with your antivirus disabled here: https://support.riotgames.com/hc/en-us/articles/224826367-Automated-Troubleshooting-Hextech-Repair-Tool .** It's a risky thing to do so don't surf in internet while doing it, just use it to only solve the problem**!!
-> Another temporary alternative might be disabling the IPv6 ON ALL **NONTUNNEL** DEVICES (not 100% sure also) - https://support.microsoft.com/en-us/help/929852/guidance-for-configuring-ipv6-in-windows-for-advanced-users
=> If it doesn't work then renable it (google it how to do it). The Antivirus way doesn't work for everybody so you will have to wait it out until they've fixed the whole situation. I keep in touch with them so I will update you guys if there's something new about it
Hope it helps, bros!
