Doesn’t look like a valid bug report since no actual info is provided other than ‘it’s only fivem, duh’ and ‘it’s the last update’ nonsense.
FYI: your controller probably has a feature called trigger haptics. You may not have noticed it before since most PC games don’t support it, including ‘normal’ GTA V.
Play on an Xbox for a change and you’ll notice it actually being ‘normal’ to have this in GTA V.
