Steam KB acting weird on desktop

The special symbols don't work for me, I've tried an external keyboard and it works perfectly, it only happens in desktop mode

Edit:
Ok, it's not that I can't write them, it's some of them that either aren't written or for example the @ Acts as a down arrow/tab or something like that, I don't understand anything

Lenovo Legion Go S
Bazzite Deck Stable

I don't think is a bug? But i don't know how to fix it
