The RiotClientServices.exe error typically indicates a problem with Riot Games' launcher or League of Legends/Valorant client. It can be caused by corrupted files, outdated drivers, conflicting software, insufficient system resources, or issues with Windows system files. The error often manifests as the launcher crashing or failing to start.
