Zoom Crashes/Microphone

After using Zoom with no issues for the past 2 years, I have recently encountered issues which are having a substantial effect on my use for work. Frequently, during a meeting, Zoom will close and then reopen again several seconds later - sometimes it doesn't reopen however and I have to reload the meeting again. This usually happens when I unmute to use the microphone, however sometimes it appears completely random. When Zoom crashes, I receive no notifications to indicate a likely cause, it simply closes and then reloads (sometimes!).

I have checked my wifi, microphone software and internet connection however these do not seem to be the cause of the issue. I have also, removed the Zoom App and reinstalled it to see if this fixes the problem, however none of these solutions have worked.
