Hey @hassanabidpk Thanks for reporting this bug. Unfortunately I can not reproduce the bug after following mentioned steps. Can you please confirm whether you are testing on the main branch or 1.3.1 version? Can you try the steps again and confirm if you still see the error? Are you doing any addition steps like pausing and resuming an export?

after clean build and fetching latest release and main branches. It worked fine. Reason for crash was that no permission popup triggered (Android 14 https://developer.android.com/about/versions/14/changes/partial-photo-video-access) in export page (for some reasons)
