Fixed|SettingsRegister: Crash if "Custom" profile does not exist
If the "Custom" profile was ever deleted or otherwise went missing, a logic error in SettingsRegister would cause a crash as it still attempted to access a profile called "Custom", expecting it always exists.
"Custom" is always supposed to exist, and will automatically be recreated if missing.
