Select all text (ctrl+a) don't work as it should be

Hi,

Im confront to a problem as I want to select a whole text in my chat bar, I would usualy do "ctrl+a" but I found out that I have to "ctrl+q". Same in the command block text input.
Somehow it work in the Minecraft launcher, I try to create a Launch options, give it a name, when I ctrl+a the text, it work, so only happen in minecraft game

My keyboard is Azerty as im French, so the key Q on my keyboard is where the A would go for a Qwerty keyboard. ( copy, past work well, only the select all feature) I tried with an other keyboard (both from Logitech) and same problem..

Somehow, it only happen in mc, anywhere else, from google to discord or any other software, the select all work fine.

 I full uninstalled it, removed the .minecraft folder, and installed it back, problem still here..

Do you have any idea ? Thanks
