I have been using kdenlive 24.05.0 on my Intel Macbook Pro on Mac OS Venture 13.6.7 for at least a month without issue. I’ve edited a number of videos without any problems. Today I went to launch it and it crashes at startup (I only get the splash screen). I tried resetting the config and even re-downloaded and installed it but no luck. If this isn’t the correct place to get assistance then please let me know where I can get help. TIA.
I have the same exact problem but on Windows 11.
I tried versions 23.08.5, 24.12.0 and even 25.03.70 with the same result.
The most frustrating part is that there is no information or log file to check what is wrong.
Could someone help me with this problem?
Hi, and welcome to the forum and community.
Please uninstall Kdenlive, delete all folders with *kdenlive* anywhere on your file system. Install Kdenlive again.
There is a Troubleshooting section in the Kdenlive Manual.
I re-installed Kdenlive as you suggeted and re-installed it again, but this time removing all reords from the registry. The result is still the same. The Event viewer shows info:
The program kdenlive.exe version 0.0.0.0 stopped interacting with Windows and was closed. (...).
So it is not very usefull and because there is no log file or any info from Kdenlive, this is looking for a needle in a haystack.
This is strange. Where did you get this from?
Secondly, the screenshot indicates a nightly build, which is a standalone (no installation needed). Please keep in mind that nightly builds are still buggy.
I strongly recommend you stay with the official 24.12 release, for which a maintenance release (24.12.1) is just around the corner.
fwiw, 25.03.70 was the snapshot JBM put up to test the first (not entirely successful) patch for the transform jitter issue - but the appimage version at least didn’t have any other issues than that.
edit: my bad … I just looked at a build from master:HEAD and it looks like it reports 25.03.70 too - I thought I’d seen some code that looked like it should mark git snapshots with git revisions, but apparently this version could be any random nightly build since November …
ah, looks like that is because RELEASE_BUILD defaults to ON - so unless the nightlies deliberately switch that off, they will all get whatever is currently in RELEASE_SERVICE_VERSION at the time
kdenlive.exe version 0.0.0.0

I found it in the Windows Event Viewer

I used to use the stable version for a while (23.08.5, then 24.12.0).
Suddenly, version 24.12.0 stopped working, so I tried other versions, including nightly build, but the result was always the same.
I did not change anything in the system or hardware configuration except for updating Windows, so maybe that’s it? But without logs this is just guessing.
Edit:
I tried to test other versions from the kdenlive repository and it seems that the latest working version is the 20.12.3. The next version, which is 21.04.0 crashed the same way as the newest one.
Do you have any idea what changed between these versions that might be causing this problem?
If the newer ones were working one day, then not at all the next - that pretty much says either you changed something on your machine or a windows update changed something on your machine.
That a really old version doesn’t have this problem says it’s probably some library or feature dependency that’s been broken - maybe by some “security” patch?
I don’t run windows so it’s hard to be much more specific - but it’s suspicious that both you and the OP had this problem “at the same time” on both Windows and Mac - and also that there aren’t lots of other people also saying they have it … but then I’m not seeing anyone say “it’s working fine for me on Win11 either …”
It’s probably going to be Something Silly - but I feel your pain while that something remains a mystery.
Silly question, but, … do you still have plenty of free disk space ?
Yes, over 180GB.
Edit:
I found the problem, at least on my machine and it is very, very unusual…
The problem was caused by… my card reader (UGREEN CR127). Once I removed it, Kdenlive started immediately.
I’m going to file that under About As Weird As It Gets! 
Is it repeatable? If you plug it back in does it crash again, or crash it if it’s already running?
Yes. I tried to plug in to different USB slots and it always caused a problem with starting Kdenlive. I also tried another card reader that I have, but it seems that only UGREEN is problematic.
Great to hear! And kudos for trying the unthinkable!
Can this thread be set to “solved” now?
I wonder if it gets mistaken for some different device - or just returns something odd or unexpectedly uninitialised when it’s probed …
That’s probably a bug in the Qt version being used for windows then rather than ‘kdenlive’ as such, and I’m not sure offhand what it is using for usb access there (libusb or some native service).
