Not sure if I’m doing something wrong as well, but sometimes this occurs for me too. Last time I noticed that restarting FiveM client (not just disconnecting!) and then rejoining helped.

My initial issue was that I noticed GetEntityHealth(player.Handle) returned always zero. This messed up my game mode as server tought the player was dead. Then I noticed that coords and heading was also wrong, but Name was still correct (just like in your case).

I just wrote this code a minute a go to check if player is in this state and then drop it from server with notice to restart FiveM:

private Dictionary<string, float> _desyncTimer = new Dictionary<string, float>();

private async Task OnCheckUnsyncPlayers()
{
    await Delay(1000);
    
    var playerList = Players;
    foreach (var player in playerList)
    {
        if (player == null || player.Handle == null || player.Character == null) continue;
        
        if (!_desyncTimer.ContainsKey(player.Handle))
        {
            _desyncTimer[player.Handle] = 0;
        }

        // if player entity stays zero health for too long, consider it as being desync
        // this has occurred few times and it ruins game mode as players coords and health is not correct
        if (GetEntityHealth(player.Character.Handle) <= 0)
        {
            _desyncTimer[player.Handle] += 1000;
    
            if (_desyncTimer[player.Handle] > 20000)
            {
                DropPlayer(player.Handle, "Please RESTART FiveM and rejoin (Reason: Desync)");
            }
        }
        else
        {
            _desyncTimer[player.Handle] = 0;
        }
    }
}

Edit:
Just use it like this:

Tick += OnCheckUnsyncPlayers;

Would be great if some one could comment what could cause this in the first place…
