Sorry to hear that! That warning is unlikely the cause of the crash, it just means that some GKT3 settings are no longer supported in GTK4 and should be removed from the settings.ini, but they do not crash the app.

Please note that our AppImage does not include the required libgkt-4-1 and libwebkitgtk-6.0-4 dependencies. I just noticed that this is not documented, my bad! Installing them will probably fix your issue.

If not or if you have any other questions, you can write me at hello@kreya.app
