Unable to enter vehicles

Recently I’ve been having a problem with all my vehicles, when I press USE it doesn’t enter the vehicles it just rotates the camera to face the other way. However this doesn’t always happen as the first time I spawn a vehicles it will let me use it but after that this bug/error occurs. I think it must be and add-on or mod that’s doing it but I thought id ask here before going through removing and testing everything (I have a lot of added stuff). Any help would be appreciated.
