Default Right Alt keyboard shortcut moves cursor one character back, can't type accents. How to disable?

Anki version:
Version ⁨24.06.3 (d678e393)⁩
Python 3.9.18 Qt 5.15.2 PyQt 5.15.5

When reviewing cards with a fill in answer, the Right Alt key will move the cursor one character back (…what?). This is a default option, and I can’t find a way to disable or change it. How can I do so?

On all my machines, the compose key for typing accents (ł, ą, etc.) has always been Right Alt. So when reviewing a card with an answer “ktoś” I will end up typing “ktśo” and get the answer marked wrong.

This strange keyboard shortcut is blocking me from studying all fill in the blank cards. Any help would be appreciated.

I’ve tried this add on, but it didn’t work. My physical keyboard has a Right Alt key, but my keyboard layout on my desktop sees it as a “ISO Level3 Shift” key. Not An Alt-Gr key.

This issue completely blocks me from using Anki, or at least on my desktop. Assigning a popular modifier key to any hotkey (and especially having no way to disable it) is very bad practice.
