I have a similar issue with Windows 10 Home. After a meeting on January 10th, I was prompted to update Zoom to Version 5.9.1. Afterward, when attempting to host a meeting today (January 11th), the client would continually "Freeze" or become "Not Responding. I was forced to conduct the meeting using my Android phone, then spent the next couple of hours after the meeting resolving the issue. I uninstalled the client multiple times with no resolution to the client "Freezing" or becoming "Not Responding". Ultimately, after uninstalling the Zoom client yet again, I downloaded the VDI Release Version 5.8.0, release date November 16th, 2021.
Everything seems to be in working order for the time being. I did a test meeting by sending an invite to a friend, and the client was able to function before the latest Version 5.9.1. Hope this reply becomes useful to others with the same issue.
