Hey Riot, so I've been trying to start up LoL for the past week or so and ever time a box pops up and tells me 'PVP.net Patcher Kernel has stopped working: A problem cause the program to stop working correctly.' Can you guys. PVP.net Patcher Kernel has stopped working? DragonKnight73 (NA) submitted in ARCHIVED Help & Support. Task Manager is useful when there is a need to close/terminate a particular running program that is frozen, not responding, taking too many CPU resources, or simply not working properly. Ending the LoL process using Task Manager might fix the 'PVP.net Patcher Kernel has stopped working' problem.
