Re: Problem with NVDA and single key navigation in Chrome
I strongly suspect that this is some sort of weird interaction between something that came preinstalled on your machine, most likely security related, and Chrome and NVDA.
There are several ways you could proceed.
1. Turning off your security software, temporarily, and if that requires rebooting then reboot, and see if the issue goes away.
2. Make sure you have already set up sound in safe mode with networking (See: Getting Sound in Safe Mode Under Windows 10) then see if the behavior occurs if you boot into Safe Mode. This avoids loading an awful lot of startup processes to begin with.
3. If either of the above fixes the issue, you will then need to follow the proper procedure to go through the process of elimination to find out what exactly is the root cause of the problem. What that is varies, so until more data is available it's really not worth going into the details.
