Hello,
I remapped the / key on the numpad (MX Keys Logitech keyboard on MacOS Ventura 13.6.4) to be able to access / and \ quickly.
It makes any apps crash.
For a bit, I had this key set up as a dead key to insert slashed letters like Ø.
Pressing the slash on the numpad would enter the relevant dead key state. Pressing the o for instance, would output the slashed-o.
I reset the key to none and the behavior persists for some unknown reasons.
