Zoom meeting keeps quitting by itself unexpectedly

My zoom meeting keeps quitting unexpectedly. Like during in the middle of a meeting, my zoom meet would just suddenly end as if it was shut off from the task manager or something. I am 100% sure this is not an internet problem. It probably ain't an account problem either. My professors in school use pro accounts so our meetings can go past 40 minutes. It also "mostly" occurs whenever I interact with another application in my desktop like Microsoft Edge. I would simply click on my browser sometimes and the Zoom meeting window would just exit by itself. There were also times where during a meeting, my entire desktop would LITERARY run in 3 fps. Yes, the entire desktop. My mouse would move incredibly slow and the sound would stutter. This would last for 5-10 seconds until the zoom meeting client would end by itself once again. Currently I'm using zoom via web browser so that it won't quit unexpectedly again but the browser version is really slow though. There must be something in my pc that keeps shutting off my zoom meeting. I didn't even receive any of those "zoom quit unexpectedly" pop-ups whenever this happens.

I really need help with this one.
