Hello,

When I work with a Krita project, there comes a time when the file doesn't open and the program closes.

Trying to open that file in different versions, I could open it with the appimage version 4.2.7

Versions of Krita that close when I open the file:
* krita 4.2.8 instalado en debian testing bullseye
* https://binary-factory.kde.org/job/Krita_Nightly_Appimage_Build/lastSuccessfulBuild/artifact/krita-4.3.0-prealpha-818c841-x86_64.appimage
* https://binary-factory.kde.org/job/Krita_Stable_Appimage_Build/lastSuccessfulBuild/artifact/krita-4.2.9-alpha-51fcc8c-x86_64.appimage
* https://download.kde.org/stable/krita/4.2.8/krita-4.2.8-x86_64.appimage


Version of Krita that opens the file:
* https://download.kde.org/stable/krita/4.2.7.1/krita-4.2.7.1b-x86_64.appimage
