If you go right with arrow, this opens right to the active menu. If you go to the left from menu item that hasn't sub menu (let's say, Navigate – Next Note), Lyx is not crashing and that opens next to the left menu.

What desktop or window manager are you using? There have been some weird

If you are able to compile LyX on your own with debug symbols (or if you
can install debug symbols on Manjaro) and get a backtrace, that would be
very useful. We can help you do that if need be.
