I just had a theory to fix it.
use an enum :

enum pData

inside it pFreeze or pCanMove or pControllable
when u wanna to freeze a player use this :

pawn Код:

PlayerInfo[playerid][pFreeze] = 1;

Then in the callback
OnPlayerStateChange
if State is passenger :

pawn Код:

if(PlayerInfo[playerid][pFreeze] == 1)
{

}

unfreeze player
remove player from vehicle
and then freeze player.

i think this is can be a fix for ur problem

This is another bug when you crouch © Change player skin with anyway, Then you got freezed.
