[CRASH] On windows 10 RS5 release candidates, game crashes after champ select
On windows 10 RS5 (fall 2018 release candidate versions of windows). After selecting a champion the game crashes before the load screen appears. The client appears with a reconnect button, but pressing it causes the game to crash again. This has started happening since version 17735 at least and continues through the latest version 17741. There is a link on the brazil forum that appears to have the same issue with the latest release candidates.

In the event log after crashing an error shows in the application log titled application error with the below text: Faulting application name: League of Legends.exe, version: 8.16.241.6543, time stamp: 0x5b6b982e Faulting module name: ntdll.dll, version: 10.0.17741.1000, time stamp: 0xff202199 Exception code: 0xc0000005 Fault offset: 0x00045930 Faulting process id: 0x3320 Faulting application start time: 0x01d439b2450fce4d Faulting application path: C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.234\deploy\League of Legends.exe Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll Report Id: b2cda2cb-709f-4338-b79b-08cf59e120de Faulting package full name: Faulting package-relative application ID:
Based on this I performed a sfc /scannow and found no issues with the dll and as this dll gets replaced during updates and the issue has survived multiple windows updates it probably isn't the ntdll.dll Additionally no other applications suffer from this issue on that version of windows.
