--- Comment #9 from Olivier F. R. Dierick o.dierick@piezo-forte.be --- Hello,
I couldn't reproduce the original issue (client crashing - not working at all), but in the current state, RiotClientServices.exe sometimes randomly crashes.
If the Riot launcher is still open when it crashes, it's still usable, but if the crash happens while the riot launcher is hidden (in the League of Legends client or in a match), the background (hidden) Riot launcher doesn't come back after closing the League of Legends client and you have to kill the background process to close it.
Regards.
