Audacity Version

stable version (from a Linux repository)

Operating system

Linux

Additional context

This is the freshly packaged version of Audacity on archlinux availiable through the testing repos.
You can check out here how it is built: https://gitlab.archlinux.org/archlinux/packaging/packages/audacity/-/blob/da3da38de951af490ff76c14de03e66f399e5047/PKGBUILD#L70-93

Maybe we missed something on packaging, but this looks like an upstream bug to me 🤔
I can also provide further debugging information if needed.

There is a similar report on the forum for a Mac user here: https://forum.audacityteam.org/t/error-report-in-audacity/89085

[christian-heusel]

This still persists for version 3.4.1 🤔

[rski]

I also encountered this while updating audacity for nixpkgs, feels related to #5004

[dozzzzer]

This will be fixed in 3.4.2

[vsverchinsky]

There is a similar report on the forum for a Mac user here: https://forum.audacityteam.org/t/error-report-in-audacity/89085

@dozzzzer MacOS crash reported on the forum is unlikely related to this exact issue, because mac build links agains another version of wxWidgets library

[christian-heusel]

Can confirm that this is fixed with audacity 3.4.2, thanks for the fix 😊 👍🏻
