Unable to enter meetings

For the past week, I can not enter meetings - and I don't get an error message.  I just end up in a loop where after I click the link (or even enter the ID number/password), I get to the launch page and nothing happens - except for the pop-up "open zoom meeting."  I click on that and I'm back on launch page.

I know the links/ids are good because can join meetings on my phone, but not on my desktop.  I updated Zoom about a month ago, and no problems until a week ago.
