My whole team got disconnected from the game, but the enemy seemed just fine :\

I don't know if this was just a bug in the client or someone was hacking or messing up something or idk... I was playing a pretty normal game then the game started to feel a bit laggy/delayed. A few minutes after the lag, my client froze and couldn't even move my mouse, 10 seconds later it unfroze but my whole team was gone meanwhile their whole team seemed fine. When they got back, I asked if their game froze too, all said yes except for our top laner that never came back.
