My NVDA is not reading any content in any of my internet browsers. I'm using NVDA 19.2 on a Windows 10 machine. I also have a portable coppy of NVDA 21.2 which also has the same issue. It says "unknown" and "content not visible" in the browser window. And, for some reason, NVDA also occasionally announces "chrome legacy window" even when I laucnch a browser other than google chrome.
This is very recent, everything was working fine till a couple of days back. Could someone please help in diagnosing the issue? Any help is much appreciated.
