I’m new to Kdenlive. I’ve just installed 26.08.0 for macOS Silicon, but the app launches, but consistently crashes When hitting the Start Editing" button to exit the Quick Setup.
I’m not sure what to try to resolve this. Any suggestions would be appreciated.
Below is an excerpt from the crash report.
