Impossible to type a left brace

[amgarcia-nape]

I've installed fvim in an ubuntu 22.04 and neovim 0.11.
I have a spanish keyboard. When I want to type a "{", typing AltGr a tooltip with apostrophe apears. I attach the image.

Had the same issue on a German keyboard.
It works with FVimKeyAltGr v:true.
