Solved! Keyboard Can't press multiple keys when key z is included

[fairys.ardhana]

Hi Guys so a week ago I asked about why my laptop can't press more than 2 keys and I thought it was just the way the keyboard was designed and it seems that I can press multiple keys at once except when the key 'z' is one of the key pressed. then i can only press 2 keys.
And in one of the game I played I need to use multiple keys at once(key z included) and I cant replace the 'move' to other key. Is there a way to fix this?
Any help is appreciated.

maybe just update the driver of your computer. Also, your keyboard is wired or wireless? if it is wireless, maybe you should also upgrade the BT.
