Anki not responding to spacebar

Hello,
I would really appreciate some help with this problem because it is making my reviews take so much longer and with the volume I am doing it is very inefficient.

I have been using it for months and today when I started using it, the app does not respond to any buttons. Spacebar works for typing this forum but when I am reviewing the space bar does not show the answer. I can use the mouse to click on “show answer” and then if I click “1” or “2” it does not respond to that. I have tried everything to restart it, restart my computer, delete anki and re install to no avail. Any idea what to do?

Thanks for the help

From the menu: Tools / Preferences / Review

Look at the checkbox that says:
☐ Spacebar (or enter) also answers card

If it is off, you want to turn it on: :ballot_box_with_check:

Please check the other shortcuts on that screen too. If they’re all ok, please try Troubleshooting - Anki Manual
