What worked for me was going to the Zoom sign-in page, right-click on the page -> “Inspect” -> “Network” tab -> Refresh the page -> Right-click on the first item “signin” -> “Clear browser cache” and “Clear browser cookies”
You can also try clearing the site-specific Cookies and Cache. Go to chrome://settings/siteData and in the Search bar on the right, type “Zoom” and delete any related items.
