Thanks for the advice. So, most of the options here I tried before (and again to be sure I wasn't missing something)

This comment is the first clue where I've seen something different..

When I alt + shift + /, in wow I finally get a "?".

In addition, I just want to reiterate this is only an issue in wow, and not in any other program. (Tried steam, a few games, email, browsers, etc). Keyboard Logitech G510s works normally in everything else. Tried this even after reinstalling, clearing the cache, interface, and wtf folder.

At least now I can get a ? mark in game, even if it's not normally how to do it, but it will still bug me forever why this is a WoW issue, and why it just started recently.

Here is a screenshot of my language settings, in case anything calls out as being off.
