League client has been freezing in game randomly for several months

Dear Rioter, So, my client freezes randomly and I have to go into my task manager and end task and reconnect client. This is been VERY frustrating as I enjoy playing ranked and it puts me and my team at a disadvantage because the game freezes. It states that it is not responding in the task manager.

No Bugsplat.

Please, I beg of thee. Sincerely,

EDIT: It happened in the first game I played so I created a dump file for someone to look at https://www.filemail.com/d/jxmzyqpnvaaswps
