Shortcut "AltGr + Q" isn't working


I recently updated Anki to 2.1.33 (from 2.1.26) and now the shortcut “AltGr + Q” (=@) doesn’t suspend cards while reviewing, although the tooltip states that it should.
In the browser/editor “AltGr + Q” works fine.
Might have to do something with the changes in 2.1.29? (“AltGr” handling)

I am using Windows 10 and I am not using any addons that change shortcuts (like “Customize Keyboard Shortcuts”).
A friend of mine has the same problem. (Same versions updated, also Win 10)

Thanks in advance!
