Anki crashes when using keyboard shortcuts to open/close dialogs

Anki Desktop
1

On Windows 10, Anki occasionally crashes when using keyboard shortcuts to open or close dialogs, e.g. when pressing B or Esc. A few versions are affected, the latest one, 2.1.49, among them. On version 2.1.49 the crash happens much more rarely than on 2.1.47, however. It happens without plugins loaded, too.

There’s no traceback. There’s a few events in the event viewer that all basically look the same:

Faulting application name: anki.exe, version: 0.0.0.0, time stamp: 0x5f2cbf6b
Faulting module name: Qt5Core.dll, version: 5.14.2.0, time stamp: 0x5e7dfaa2

Faulting package-relative application ID:

Is there anything I can do to debug this further?

Can you reproduce it in both the qt5 and qt6 builds? Changes in 2.1.50 - Anki Betas

@Rumo Have you ever seen this on your Windows machine? I don’t recall ever seeing it in testing.

@oakkitten One possibility is it’s something specific to your machine, like your video driver or the presence of some other utility. I’m afraid I’m not sure how you could narrow it down further, except for trying to change the video setting in Anki’s preferences, or trying Anki in Windows safe mode.

I haven’t seen that, either.
