Hello,

I am experiencing crashes when undoing a card on Anki desktop flatpak.  
It happens consistently when inputting “Ctrl-Z” while in review mode a deck, or upon clicking “Other choices” in review mode.

No error log while starting anki via terminal.

Here is some info about my system :

OS: Fedora Linux 44.20261004.0 (Silverblue)

Anki version : Version ⁨26.09.3 (29bb700b)⁩  
Python 3.13.15 Qt 6.11.2 Chromium 140

Flatpak provider : net.ankiweb.Anki

Do you have a fix for this behavior ? Do other people experience it aswell ?

Have a good day.

Can you try switching the video driver? See [Troubleshooting - Anki Manual](https://docs.ankiweb.net/troubleshooting.html)

I recommend checking all other steps too, especially 2 and 7.
