This is a bug that has happened to quite a few people I know

When I try to give it F3 + G to see the chunks in my survival, it does not go, it does nothing, surprised, thinking that it is my keyboard, I give it to F3 + Q and it goes, half or less of the combinations of the F3 do not go, F3 + H, F3 + T

I have tried on another computer and all F3s work perfectly

Some time ago, in the 20w20 snapshot I was leaving.
