Can't type lowercase "G" on GNOME 44.2

Every time I try to type a lowercase “G”, it acts like the compose key was pressed (It’s not, this also occurs if the compose key is disabled). So, instead of typing “G”, the “G” and the following letter just disappear. Also, pressing “G” and space doesn’t work.

Additionally, changing keyboard-layouts didn’t help either.

You could do some testing - install package xorg-xev

From Keyboard input - ArchWiki

 $ xev | awk -F'[ )]+' '/^KeyPress/ { a[NR+2] } NR in a { printf "%-3s %s\n", $5, $8 }'
42  g
62  Shift_R
42  G
50  Shift_L
42  G

Trying this, it looks like the G-key is properly recognized:

$ xev | awk -F'[ )]+' '/^KeyPress/ { a[NR+2] } NR in a { printf "%-3s %s\n", $5, $8 }'                                                                                                                                                   ─╯
