Can’t join or start a meeting

I can’t join a meeting or start one. When I press the button to join, the screen turns white for a few seconds, and I don’t get the option to enter the code. The same thing happens when I try to start my own meeting or open the settings. I have the latest version of the app, and my system is Windows 11. I’ve already uninstalled and reinstalled the app, cleared the cache, and switched browsers, but it still doesn’t work.
