Things to try:

1. Go to openshot.org/download/#daily and download the latest dev daily build (v3.3.0) AppImage. Make it executable and run it. You need to install libfuse2 for the AppImage to run.
2. Ensure you have plenty of free hard drive disk space. Free up as much as possible.
3. Make a backup of /home/username/.openshot_qt folder.
4. Delete /home/username/.openshot_qt folder.
5. Start OpenShot, open your project and test the Export. If you still get the same error message then continue....
6. Restart your computer.
7. Start the downloaded AppImage and a new project.
8. Import each source file one at a time. Drag it onto Track 5 and save the project. Export without any changes.
9. Repeat step 8, importing the 2nd, 3rd,....etc. source file and continue Exporting until you get to a point where the crash happens. Obviously after you Export with all 6 source files, go ahead and make the cut on the 6th clip and Export again.

Essentially, we are trying to figure out where the problem surfaces so we can troubleshoot further.

I have same issue with exporting video.

I added to project 1 video 1 min 20 sec, cutted fragment from it (about 15 sec), and tried to export.

Error: std::bad_array_new_length

• Platform: Fedora 41
• Package: openshot-3.2.1-2.fc41.noarch
• Kernel: Linux 6.13.12-200.fc41.x86_64 #1 SMP PREEMPT_DYNAMIC Sun Apr 20 15:52:43 UTC 2025 x86_64 GNU/Linux
• Machine: x86_64

I installed OpenShot RPM using Discover (in KDE).

Short update: I created new project, just added 1 min video and then tried to export. Same error, std::bad_array_new_length

So, bug is not related to cutting video and using later 2 clips.

Tried OpenShot 3.3.0 AppImage from https://www.openshot.org/download/ I can confirm that export of videdo in ver.3.3.0 AppImage works. Besides, icons in toolbar are also visible (they were invisible in openshot-3.2.1 in Fedora 41 distribution)
