Windows 10 & "LolClient.exe has stopped working"

I'm someone who was fortunate enough to never have problems with the client while using previous operating systems, but since upgrading to Windows 10 64-bit, I've twice had "LolClient.exe has stopped working" in the last week. Thankfully both times this happened I wasn't in a game nor in a game lobby, just sitting at the main screen. If it matters, I did a clean installation of Windows 10, not upgrading from a previous operating system.

I was able to find the crash in the Event Viewer:

DxDiag is attached as well.
