Kdenlive not opening

Suddenly it won’t open. OK this morning when I added a second screen, switched off over lunchtime, back on but all I get is an error message

Running on Mac mini M4 and version 25.12.1. I uninstalled and re-downloaded but still keep getting this error message, no idea what’s going on.

I’m going to take a shot in the dark here with this: did you double click on it while it was in the DMG file? I’ve seen similar bug reports for Tahoma2D and the dev each time recommends extracting the DMG first.

Thanks for the reply, lost hope of it ever working. Seeking an alternative app.

Is this relevant ?

I have the same problem with a mac mini M1. It happens with version 25.12.0 and

still the same with 25.12.1.

Maybe try 25.12.2 since there is a fix for macOS in it ?

I tried 25.12.2 and it’s still the same. It opens the first window and it’s impossible to open an existing project.

To be more precise, it’s also impossible to open a new project.

It worked on my test system. Could you tell us which MacOS version you have?

Oh sorry I see it’s 26.2 in the crash log. Will test again in the next days.
