Lol, had the exact same thing happen to me about 6 weeks ago. Here’s how to fix things. Kudo’s to Jackie for this fix.
1) Press NVDA+ctrl+g to access the general settings dialog.
2) At this point, you're in a dropdown list. Hit home, then type e for english.
3) Shift tab twice to 'apply' & activate the button.
4) You'll be asked to restart. If you hit enter, NVDA will restart &
your changes should take effect permanently.
Hope this helps
