New update, zoom response is very slow and lagging

I'm using 1GB LAN and

Samsung Pen laptop

Zoom Meeting Desktop Client is up-to-date(new update last night)

No error codes, however, ever since I've updated, I've noticed that the buttons won't response quickly.

Even the audio(from host's microphone) lags from time to time by few seconds. It will eventually go back to normal but sometimes it lags. We're doing online teaching so this is a serious problem for us.

Anyone else experiencing something similar?
