I see from your log file that you've been upgrading/downgrading with v3.1.1, v3.3.0, v3.4.0, etc.

From the log file I couldn't tell exactly which flavor of Linux you are running so it would be great if you share that with us.

1. Are you using Headphones by any chance? If yes, unplug them.
2. Close OpenShot, if running.
3. Make a backup of /home/username/.openshot_qt folder.
4. Delete /home/username/.openshot_qt folder.
5. Download build #16416 dev daily build Appimage instead of 16422.
6. Make it executable and run it.

Let us know if the error persists.
