Mack book become very sluggish after an hour of video chat
I recently noticed that, my Mac Book pro becomes very sluggish after 45 minute of video meeting, and finally, it stopped responding. I ended up rebooting to reconnect the video chat. This was using Zoom.
Next time I had a video chat, I closed most of the applications, just to avoid the problem. This time my meeting was in a (chrome)browser video(something custom) after 45 minute, I again started to noticed the sluggishness, I immediately closed the Xcode, which was the only other app running except my chrome browser, and thus I was able to avoid the problem.
This problem started happening very recently, In the past I have had 3-4 hours of video meeting without any problem. I currently Have MacOS Big Sur 11.4. I am wondering what is going on, how to avoid this problem? Any help is appreciated.
Thanks
MacBook Pro 13″, macOS 11.4
