Hey Apollo, thanks for the reply.
So the key works in other programs, I have a second keyboard and it has the same issue.
A few other keys don't work, I can do a "/" but not a "?" . Since the issue only happens in my EO client I suspect it has something to do with it but I can't for the life of me figure out where the conflict is.
Edit: So it is some conflict with something on my laptop. My PC EO client is fine. I blame windows 11 -.-
